Question

How much energy is required to activate a chemical reaction with a rate constant of 2.5x10^-3 s^-1 if the activation energy is 50 kJ/mol?

Answer 1

The energy required to activate a chemical reaction is given by the activation energy  Ea . In this case, the activation energy is already provided as 50 kJ/mol. Therefore, the energy required to activate the chemical reaction is 50 kJ/mol. The rate constant  k  is not needed to determine the activation energy.
