If the activation energy of a reaction is 80 . 9 kJ mol - 1 , the fraction of molecules at 700 K , having enough energy to react to form products is e - x . The value of x is (Rounded off to the nearest integer) [Use R = 8 . 31 J K - 1 mol - 1 ]

Correct answer

0

Step-by-step solution

Fraction of molecules to have enough energy to react = e - Ea / RT So, x = E a RT = 80 . 9 × 10 3 8 . 31 × 700 = 13 . 9 ≈ 14
