Consider the following statements.
I. In general, the temperature dependence of the equilibrium constant depends on the sign of $∆\mathrm{H}$ for the reaction.
II. The equilibrium constant for an exothermic reaction (negative, $∆\mathrm{H}$)decreases as the temperature increases.
III. The equilibrium constant for an endothermic reaction (positive,$∆\mathrm{H}$)increases as the temperature increases.
IV. Temperature changes affect the equilibrium constant and rates of reactions.
Choose the correct statements.
