Re: Liquids and Solids in Equilibrium Calculations

Yes, but it depends on the solvent! The solvent is never involved (most of the time it's water) but water is apart of the reaction so include it when there is another inert solvent being used.

Don't think of this as a math rule... think of it conceptually. Under what conditions can X be emitted? This would be when the K value is extremely small, that it doesn't make a difference.

Re: Enthalpy vs Temperature

Temperature describes the temperature at which a reaction takes place. Enthalpy describes the change in heat from the reaction itself.

Re: Standard Enthalpy

Standard Enthalpy, or delta h0, is just the enthalpy of a reaction at STP conditions. Standard Enthalpy of Formation is the delta H of a reaction forming a molecule at STP, with the reactants all being in their standard forms.

Re: Sapling Week 1 #10

Basically, you can set up an ICE table using the equilibrium concentrations from earlier to help provide initial concentrations before the addition. After the addition of NO2, our new initial concentration of NO2 is 3.05 mol. For the initial N2O4, it is the same as the equilibrium concentration. Now...

Re: Adding more of only one reactant

I agree with Andreas's response, the reaction would be at a Q value different from K, meaning that after that reactant is added the system is no longer at equilibrium. However, it is not possible for the reaction to be completely limited by B because the reverse reaction still takes place. Remember,...
