A reaction having equal energies of activation for forward and reverse reactions hasA reaction having equal energies of activation for forward and reverse reactions has

Options

  1. AΔS=0\Delta S=0
  2. BΔG=0\Delta G=0
  3. CΔH=0\Delta H=0
  4. DΔH=ΔG=ΔS=0\Delta H=\Delta G=\Delta S=0

Correct answer

C. ΔH=0\Delta H=0

Step-by-step solution

Energy profile diagram for a reaction is as From the figure, it is clear that A reaction having equal energies of activation for forward and reverse reactions has
So, ((E2)b=(E2)f+ΔH()as,((E2)b=(E2)f)So,(ΔH=0).[Here\left(E_2\right)_b=\left(E_2\right)_f+\Delta H\left(\right.) as, (\left(E_2\right)_b=\left(E_2\right)_f) So, (\Delta H=0). [Here\left(E_2\right)_b=activationenergyofbackwardreactionand(E2)f=activation energy of backward reaction and \left(E_2\right)_f= activation energy of forward reaction].
