Multiple Choice Options

  • A Formation of A and B from C has highest enthalpy of activation.
  • B D is kinetically stable product.
  • C C is the thermodynamically stable product
  • D Activation enthalpy to form C is 5kJ mol–1 less than that to form D.

Step-by-Step Verified Solution

JEE Main 2019 (Online) 9th April Evening Slot Chemistry - Chemical Kinetics and Nuclear Chemistry Question 126 English Explanation

∴\therefore E aa = (A + B) →\to C = 15

E aa = (A + B) →\to D = 10

So, Activation enthalpy to form C is 5 kJ mol-1 more than that to form D.
