Energy of activation of forward reaction for an endothermic process is 50 ~kJ . If enthalpy change for forward reaction is 20 ~kJ then enthalpy change for backward reaction will be

Options

  1. A30 ~kJ
  2. B20 ~kJ
  3. C70 ~kJ
  4. D50 ~kJ

Correct answer

A. 30 ~kJ

Step-by-step solution

For endothermic reaction, E_ a, b =E_ a, f - H^ =50 ~kJ -20 ~kJ =30 ~kJ
