Rate of which type of elementary reaction increases with increase in temperature? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

For any elementary reaction, the rate constant is given by K = A*e^(-E_a/RT). Since the activation energy E_a of an elementary reaction is always positive, an increase in temperature T always increases the value of the exponential term e^(-E_a/RT), and thus the rate constant K increases. This applies to all elementary reactions, regardless of whether they are exothermic, endothermic, or thermal.
