Homework 5G.21

Postby Eileen Si 1G » Wed Feb 19, 2020 9:52 pm

For homework problem 5G.21, it asks to calculate the equilibrium constant at 25 C for the following reaction, by using data in Appendix 2A: 2H2(g) + O2(g) = 2H2O(g). I know that you have to use the equation, delta G=-RTlnK in order to solve for equilibrium constant, K, but would delta G be the delta G of the whole reaction or just delta G of 2H2O(g) since this is the final product of the reaction?

Delta G is for the whole reaction, which can be calculated using the standard gibbs free energy of formation for the products and reactants.
