Practice: Consider a reaction where K_{eq}=1.6 but Q = 3.19. What direction will the reaction proceed?

Practice: At equilibrium, the reaction A ⇌ B + C has the following reactant concentrations: [A] = 3 mM, [B] = 4 mM, and [C] = 10 mM. What is the standard free energy change for the reaction & is it endergonic or exergonic?

Practice: ΔG˚=141.7 kJ for the following reaction. Calculate ΔG: T=10˚C, [SO _{3}] = 25mM, [SO_{2}] = 50mM, & [O_{2}] = 75 mM.
