For this problem, we have to determine if the reaction is exothermic or endothermic using the provided temperature and K value
Consider a galvanic cell that uses the reaction
4H3O+ (aq) + 4I- (aq) + O2 (g) → 2I2 (s) 6H2O (l).
The equilibrium constant for the reaction at 125 °C is measured to be 1.68 x 1033. Is the reaction endothermic or exothermic? Show all your work and circle your final answer.
