Question

The number of molecules with energy greater than the threshold energy for a reaction increases five fold by a rise of temperature from 27 °C to 42 °C. Its energy of activation in J/mol is ___. (Take In 5 = 1.6094; R = 8.314 J mol^-1 K^-1)

Answer 1

T₁ = 300K T₂ = 315K

As per question K_T2 = 5K_T1 as molecules activated are increased five times so k will increases 5 times
