Question

The first order rate constant for the decomposition of ethyl iodide by the reaction 

C₂H₅I (g) → C₂H₄ (g) + HI (g)

at 600 K is 1.60 x 10^-1 s^-1. Its energy of activation is 209 kJ / mol. Calculate the rate constant of the reaction at 700K.

Answer 1

Given T₁ = 600 K

k₁ = 1.60 x 10^-5 sec^-1

T₂ = 700K

k₂ = ?

E_a = 299 kJ mol^-1 = 299000 J mol^-1

Substituting these values in the equation.
