We’re being asked to determine the temperature at which the rate constant of a reaction is 1521 s–1


We’re given the rate constant at another temperature and the activation energy of the reaction. This means we need to use the two-point form of the Arrhenius Equation:



where:

k1 = rate constant at T1 

k2 = rate constant at T2 

Ea = activation energy (in J/mol) 

R = gas constant (8.314 J/mol•K) 

T1 and T2 = temperature (in K).
