Which of the following is definitely true, if for a reaction activation energies of forward and backward reactions are equal?

Options

  1. AΔH = 0
  2. BΔG = 0
  3. CThere is no catalyst
  4. DThe order is zero

Correct answer

A. ΔH = 0

Step-by-step solution

We know that ∆ H = E a forward - E a backward If the activation energies of both forward and backward reactions are the same, then ∆ H = 0 . We can't comment anything about ∆ G , catalyst or order of reaction till we have any other supporting data.
