Question

plzz solve question no. 4.30

Answer 1

I am not sure but I think this is possibility

use Arhenius formula,

log( K1/K2) = Eg/2.303R [ 1/T1 - 1/T2]

rate of reaction goes to quadruple when temperature change , 293 to 313 K

we Know,
rate of reaction directly proportional to rate constant
e.g
d[A]/dt =K[A]ⁿ

so, K2 = 4K1

log(4K1/K1) = Eg/2.303 R[ 1/293 - 1/313 ]

log4 = Eg/2.303 R( 20)/293 x 313

Eg = log4 (2.303R) x 293 x 313/20

Eg = 52982.74 jule
=52.98274 KJ
