Problem: Two reactions have identical values for Ea. Does this ensure that they will have the same rate constant if run at the same temperature?

FREE Expert Solution

We have to determine if two reactions with the same activation energy would have the same rate constants if they are run at the same temperature.

We will use the two-point form of the Arrhenius equation to solve this problem.

lnk2k1 = -EaR(1T2 - 1T1)

Where,

k1 = rate constant at T1

k2 = rate constant at T2

Ea = activation energy

R = universal gas constant

T2 = higher temperature

T1 = lower temperature
