💡 Solution & Explanation

For an exothermic reversible reaction, the activation energy of the backward reaction is greater than that of the forward reaction. Increasing the temperature increases the rate of the backward reaction more drastically than the forward reaction (higher temperature coefficient for higher Ea), which can result in a net decrease of the overall reaction rate. Therefore, correct answer is A.
