Consider an endothermic reaction, X Y with the activation energies E_b and E_f for the backward and forward reactions, respectively. In general

Options

  1. AE _ b < E _ f
  2. BE_b>E_f
  3. CE_b=E_f
  4. DThere is no definite relation between E_b and E_f

Correct answer

A. E _ b < E _ f

Step-by-step solution
