1. Write the equilibrium constant expression for each of the following reactions. a. CO3(aq) + H2O(1) HCO3(aq) + OH(aq) Keq = b. 2 KClO3(s) 2 KCI(s) + 3 O2(g) Keq = c. HF(aq) + H2O(1) H3O+ (aq) + F (aq) Keq = d. NH3(aq) + H2O(1) NH4+ (aq) + OH(aq) Keq = 2. For the reaction C(s, diamond) → C(s, graphite), AG = -2.9 kJ/mol. a. According to this information, do diamonds spontaneously turn into graphite? circle one: yes no b. In light of your answer to part (a), why can diamonds be kept unchanged for thousands of years?
