The rate constant is given by the equation: K = P × A × e^(-E_a/RT). Which factor should register a — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

To make a reaction proceed more rapidly, the rate constant K must increase. In the Arrhenius equation K = P × A × e^(-E_a/RT), K is exponentially related to -E_a. A decrease in the activation energy (E_a) decreases the height of the energy barrier, thereby increasing the fraction of active collisions and making the reaction proceed faster.
