Consider the reaction A+B --> C where dG'=63 kJ/molK at equilibrium. For a given set of reaction conditions, pretend you calculated dG=80kJ/molK.
a. Write an expression for Kp for the hypothetical gas phase reaction A(g) + B(g) --> C(g).
b. Is the reaction at equilibrium?
c. If its not at equilibrium, which way will it shift to re-establish equilibrium?. If it is at equilibrium, just type N/A.

The general form of a chemical reaction is aA + bB = cC +dD Where A and B are reactants in the forward direction and C and D are products in the forward direction. The lower case letters are the stoichiometric coefficients for the balanced equation. The general form of the equilibrium constant equation is then: Keq = [C]c[D]d/[A]a[B]b Part I: Q vs. K Q: reaction quotient can be calculated for a reaction at any concentration values of reactants and...
