The activation energy for a simple chemical reaction A B is E_ a in forward direction. The activation energy for reverse reaction

Options

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

Correct answer

B. can be less than or more than E_ a

Step-by-step solution

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