Question

The rate constant of a reaction increases by five times on increase in temperature from 27°C to 52°C. Thevalue of activation energy in kJmol^-1is ____. (Rounded off to the nearest integer) (R=8.314JK^-1 mol^-1)

Accepted Answer

Correct answer: 52. 52 K_52°CK_27°C=5 ln ( kT_2kT_1 )= E_aR( 1300- 1325) 2.303 0.7 8.314 300 32525=E_a E_a=51524.96 J/mol E_a=51.524 KJ/mol 52

$The rate constant of a reaction increases by five times on increase in temperature from 27°C to 52°C. Thevalue of activation energy in kJmol^{- 1} is ____. (Rounded off to the nearest integer) (R = 8.314 J K^{- 1} mol^{- 1})$
