ChemistryNEET 2021Arrhenius equation and activation energy

Chemical Kinetics

For a reaction A → B, the enthalpy of reaction is −4.2 kJ mol−1-4.2\ \mathrm{kJ\,mol^{-1}} and the enthalpy of activation is 9.6 kJ mol−19.6\ \mathrm{kJ\,mol^{-1}}. The correct potential energy profile for the reaction is shown in option:

Question 83 as printed in the NEET 2021 booklet

  1. A.Profile (1)
  2. B.Profile (2)✓
  3. C.Profile (3)
  4. D.Profile (4)

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
