Question

$\bf{\fbox\red {Chemical kinetics}}$

♣Explain Briefly♣​

Answer 1

Answer:

(d) all the options are correct

Explanation:

Threshold energy is equal to Activation energy and normal energy

15 + 10 = 25

A is correct

As threshold energy from reactant side or product side is equal,

15 + 10 = 9 + PE of Y

=> PE of Y = 16

B is correct

Heat of reaction = Activation energy of X - Activation energy of Y

=> Heat of reaction = 15 - 9 = 6

C is correct

As Heat of reaction is positive, it is endothermic

D is Correct

hence, all options are correct
