Re: third order

In lecture he mentioned that they are unlikely and he placed more emphasis on understanding the 0th, 1st, and 2nd order.

Re: Questions on Final

I would expect there to be more emphasis on questions regarding electrochemistry and kinetics, with the same format/style as the midterm questions but he didn't specify.

Re: Q VS. K

K is the reaction at equilibrium and Q is used to calculate the ratio at anytime, but they are both calculated the same way. If Q<K then the reactants are favored and will shift towards the products (forward. If Q>K then the products are favored and will shift towards the reactants (reverse).

Re: removing heat from system

Even though the temperature doesn't always change, knowing if the reaction is exothermic or endothermic helps indicate the enthalpy.

Re: Isothermal

It will usually indicate that the temperature is constant, but it is safe to assume that the reaction is isothermal.

Henry Dudley 1G wrote:Can a bimolecular reaction be third order if one of the reactants is second order?

I believe in lecture he showed that a bimolecular reaction was specifically related to reactants that are/add up to second order only. For third order (which he said was unlikely) they were labeled as termolecular.

Re: Final

It helps doing practice problems and going over problems in the exams and midterms. Also, it's ideal that you understand how to use equations and understand how some relate to each other.

Re: Test 2

Delta G would be less than zero because combustion releases heat and is spontaneous.

Re: Intermediate species

An intermediate species is temporary during a reaction that helps it go to completion. Despite this, it is not normally produced at the end.

Re: Meaning of Zero, First, and Second Order?

The orders correspond to the sum of the reactants' individual orders. It's helpful looking at the particular graphs to determine the overall reaction order.

Re: n

In lecture he said that n is based on the number of moles of electrons gained/lost in the redox reaction.

Re: Reducing Agent/ Oxidizing Agent Strength in Metals

The metal is stronger as a reducing agent when the standard potential is more negative and vice versa when the standard potential is more positive, the metal is stronger as an oxidizing agent.

Re: Balancing Redox Reactions

The reaction was reversed because it was Cu that was being oxidized during the reaction, meaning that it occurred in the anode.

Re: Moles of electrons?

It helps to balance out the half reactions to see how many moles of electrons are gained/lost.
