Re: Rate Determining

If they give you graphs with activation energy, the graph with the higher activation energy will be slower than the other bc it will take longer and more energy to carry out the reaction.

Re: Isothermal system

Work = 0 in free expansion because there is no external pressure applied, so P=0 and therefore w=0. Since ΔU = 0, that means that q=0 as well, so no heat is transferred into the surroundings.

Re: When to use ICE table?

You can use ICE tables for finding equilibrium concentrations and initial concentrations but you can also use them to find the pH of an acid or base. For instance, to find the pH, you would do -log(x) where x is the change in concentration (C part of the ICE table).
