For a reaction `A_(2) + B_(2) hArr 2AB` the figure shows the path of the reaction in absence and presence of a catalyst. What will be energy of activation for forward `(E_(f))` and backward `(E_(b))` reaction in presence of a catalyst and `Delta H` for the reaction? The dotted curve is path of reaction in presence of a catalyst. A. `E_(f) = 60 kJ// mol, E_(b) = 70 kJ // mol, Delta H = 20 kJ// mol`B. `E_(f) = 20 kJ mol, E_(b) = 2- kJ// mol, Delta H = 50 kJ//mol`C. `E_(f) = 70 kJ//mol, E_(b) = 20 kJ//mol, Delta H = 10 kJ//mol`D. `E_(f) = 10 kJ//mol, E_(b) = 20 kJ//mol, Delta H = - 10 kJ mol` |

Answer» Correct Answer - D `E_(f) = 70 - 60 = 10 `kj/mol `E_(b) = 70 - 50 = 20` kj/mol `Delta H = 50 - 60 = - 10` kj/mol |
