It is a linear line with a positive slope since k is positive.

Calvin Patel 2H

If there is no solid present, then you can add in Pt to make the cell diagram.

Calvin Patel 2H

Use the reduction potential of the Cathode and the Anode.

Calvin Patel 2H

Yes, it is independent of concentration.

Calvin Patel 2H

One thing I do is that I go on the Syllabus and it lists practice problems for each topic. So i go over those and try to understand them conceptually.

Calvin Patel 2H

No but it will help to kind of understand it. Just the basics of it

Calvin Patel 2H

It means that it can be first order with one of the reactants, but the overall order could be second order.

Calvin Patel 2H

Aqueous in the middle and solids on the outside.

Calvin Patel 2H

Thermo deals with change in energy. Kinetics deals with change in rxn rates

Calvin Patel 2H

The reversibility of it makes energy and allows it to do work. If it were not reversible, there would be no production of energy.

Calvin Patel 2H

E^o cell is used when under standard conditions. E cell is under "nonstandard" conditions.

Calvin Patel 2H

You would put the H+ with the Cr2O7 since the oxygen atoms are balanced with H20, and the H20 is balanced with the H+

Calvin Patel 2H

Melting ice is a spontaneous reaction, and a negative Gibbs Free Energy indicates a spontaneous reaction.

Calvin Patel 2H

zero order: M/s
1st order: 1/s
2nd order : 1/(M*s)

Calvin Patel 2H

You can use either, but if you are converting between ln and log, use lnx=2.303logx

Calvin Patel 2H

you could also always graph the data and see which one is linear and then compare it to the first and second order rxns

Calvin Patel 2H

The average rate is the rate over a given interval of time. Instantaneous rate is the rate at a given moment in time

Calvin Patel 2H

Yes. There are 3rd and 4th order reactions, but we don't need them for this class

Calvin Patel 2H

I think as long as you know the conversions between torr, bar, and atm, you'll be fine. Although I am not sure if he will give the values on the test or not.

Calvin Patel 2H

you could write mol*L^-1 or M or mol/L

Calvin Patel 2H

The degree symbolizes that it is occurring at standard conditions of 1atm. There can be instances where there is no degree symbol and that means that there is a change in the standard conditions.

Calvin Patel 2H

Adding an inert gas does change the pressure, but since the change in pressure was not caused by a change in volume and since the inert gas does not have any effect on the reaction, there will be no change in equilibrium.

Calvin Patel 2H

In an open system, there is a possibility for matter to exchange with the solution since it is open and matter can be exchanged with the surroundings. However, in a closed system, only energy can be exchanged since the system is closed so no matter can enter or exit.

Calvin Patel 2H

If you look at partial pressure as concentrations, if you increase the partial pressure of the reactants, the reaction will favor the products. If you increase the partial pressure of the products, the reaction will favor the reactants.

Calvin Patel 2H

Yea. As long as we label it as what it is we are doing, it won't matter which ones you do

Calvin Patel 2H

Hey. I am still confused on the relation between Degeneracy and Entropy. Like if one increases does the other? Or how does the relationship work?

Calvin Patel 2H

Technically an increase in pressure will favor the side with less moles, but it also depends on other factors such as if it is an inert gas or if there is a change in volume with the reaction.

Calvin Patel 2H

If you increase the pressure, the reaction will favor the side with less moles.

Calvin Patel 2H

A negative q signifies that the reaction is exothermic and that heat is being released with the reaction.

Calvin Patel 2H

It is because you cannot compress a solid or liquid like you can to a gas. So therefore, the pressure and change in volume are negated since it won't make a difference.

Calvin Patel 2H

With a closed system, there is still an exchange of energy with the surroundings. But, with a sealed system, there is no exchange of energy or matter with the surroundings.

Calvin Patel 2H

Just a quick question, would there be a difference in Kp and Kc if you are dealing with gases. Like, wouldn't both values be the same?

Calvin Patel 2H

Usually you would want to use either the enthalpy of formation or of combustion methods. These are the most accurate and easiest to use. Using the mean bond enthalpy is less accurate and it can get confusing at times. It really depends on what equations you are given and what values you know. There...

pKa is the -log(Ka value). pH is the -log(H3O+ concentration). If you are given the pH, you can use 10^-(pH value) and find your H3O+ concentration. Then you can set up an ice table and find the values at equilibrium and use those values to find the Ka value and pKa value.

Calvin Patel 2H

There may also be situations where you could just use the basic outline for a chemical equation (HA, H3O+, OH-) if you know how the reaction proceeds. This could help you save time and make the problem easier instead of spending too much time getting the equation correct.

Calvin Patel 2H

Amphoteric means that the substance can act as either an acid or a base. Amphiprotic means that the the substance can both and accept donate hydrogen ions (aka protons). All amphiprotic substances are also amphoteric (donate hydrogen ions (act as an acid) or accept a hydrogen ion (act as a base)). B...
