We’re being asked to list the given reactions in order of increasing activation energy based on the given plots:



We’re given the plot of ln k (y) vs. 1/T (x)


This means we need to use the two-point form of the Arrhenius Equation:


ln k=-EaR 1T + ln A


where: 

k = rate constant

Ea = activation energy (in J/mol)

R = gas constant (8.314 J/mol • K)

T = temperature (in K)

A = Arrhenius constant or frequency factor
