NEETChemistryThermodynamicsMCQ+4 / −1
A reaction having equal energies of activation for forward and reverse reactions has
  1. A
    Δ\DeltaΔH = 0
  2. B
    Δ\DeltaΔH = Δ\DeltaΔG = Δ\DeltaΔS = 0
  3. C
    Δ\DeltaΔS = 0
  4. D
    Δ\DeltaΔG = 0
View written solutionFree

Correct answer: A

For a general reaction,

ΔH = Activation energy of forward reaction – Activation energy of backward reaction.

As, both the energies of activation have same value thus, ΔH = 0.

Δ\Delta ΔG is not equal to zero because if it is so the reaction must be in equilibrium which is not in this case
