Re: Closed and Isolated

Why would a plant be seen as an open system? Why is it not multiple closed systems? wouldn't a cell be a closed system?

Re: pKa

pKA and pH tend to have different values. While pH is just a way of seeing the concentration of hydrogen by the scale of ten, pKa is a way of seeing the Ka by the scale of ten. The Ka is a number used to describe the relation between products and reactants. that is why its concentration of products ...

Re: Why do stronger bases have conjugate acids with larger pKa values?

Stronger bases have conjugate acids that are weak. Since weak acids have large pKa values, the conjugate acid has a large pKa. This is because in the same way that the lower the pH the more acidic a substance is, the lower the pKa the more acidic it is as well.

Re: Temperature Relation

temperature is also related to the speed at which particles move and collide. If the object has higher temperature, the particles move faster. This means more collisions therefore more reactions which completely changes the rate of reaction. K value is the equilibrium constant and is completely depe...

Changes to K value

What factors effect the K value and which do not? (for example temperature, pressure, volume, concentration)

Re: p. 435 Gibbs Free Energy Curve

Graph A shows the energy level of a reAction with a K value greater than 1. This means that the reaction is product favored in that more products are formed. This means that these products are more stable than the reactants and this is shown in the graph as the more stable something is, the less fre...

Re: New to Lavelle

As someone new to Lavelle I would like to ask, how well do the lectures prepare us for the midterm and final ? Is watching the modules absolutely necessary to ace this class or do the lectures go over all the topics well enough ? Also, how rigorous are the tests (not the final and the midterm the ot...
