Problem: Consider a galvanic cell that uses the reaction4H3O+ (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.
FREE Expert Solution
For this problem, we have to determine if the reaction is exothermic or endothermic using the provided temperature and K value
- Recall that if K > 1, the forward reaction of the equilibrium is favored
- Notice that K is very high at 1.68 x 1033 which means products are produced
