List of top Chemistry Questions on Activation energy

Pre-exponential factors of two different reactions of same order are identical. Let activation energy of first reaction exceed the activation energy of second reaction by 20 kJ mol\(^{-1}\). If \(k_1\) and \(k_2\) are the rate constants of first and second reaction respectively at 300 K, then \(\ln \frac{k_{2}}{k_{1}}\) will be___. (nearest integer) [\(R=8.3 \text{ J K}^{-1} \text{ mol}^{-1}\)]

Consider the given figure and choose the correct option:

Consider the following graph between Rate Constant (K) and \( \frac{1}{T} \): Based on the graph, determine the correct order of activation energies \( E_{a1}, E_{a2}, \) and \( E_{a3} \).

The Activation energy for the reaction A $\rightarrow$ B + C, at a temperature $T_K$ was 0.04606 RT J/mol. What is the ratio of Arrhenius factor to the Rate constant for this reaction?
