Step 1
Given that, a First order reaction has
Temperature T1 = 24°C = 297 K
Rate constant k1 at T1 = 2.05×10-2 s-1
activation energy = 125 KJ/mol
And temperature T2 = 58°C = 331 K
Rate constant k at T2 = to be calculated.
Arrhenius equation for the rate constant k1k can be written as:
k1 = Ae-Ea/RT1 ... (1)
and for the rate constant k can be written as;
k = Ae-Ea/RT2 ... (2)
