Based on the information given, it has been computed that the activation energy will be 105.8Kj.

<h3>How to calculate activition energy</h3>

From the information given,

T1 = 25 + 273 = 298K

T2 = 35 + 273 = 308J

R = 8.314J/mol

K2/K1 = 4

Therefore,

log(4) = E/(2.303 × 8.314) × [10/(298 × 308)]

= (0.602 × 2.303 × 8.314 × 298 × 308) / 10

= 105.8KJ

Therefore, the activation energy is 105.8KJ.
