The activation energy for a simple chemical reaction A→B\mathrm{A} \rightarrow \mathrm{B} is EaE_{a} in forward direction. The activation energy for reverse reaction

Options

  1. Ais always less than EaE_{a}
  2. Bcan be less than or more than EaE_{a}
  3. Cis always double of EaE_{a}
  4. Dis negative of EaE_{a}

Correct answer

B. can be less than or more than EaE_{a}

Step-by-step solution

Since the nature of reaction (i.e. exothermic or endothermic) is not given, Ea\mathrm{E}_{\mathrm{a}} for reverse reaction can be more or less.
