The rate constant for the rxn of hydrogen reacting with iodine to form hydrogen iodide is 2.7 X 10^-4 L/mol*s at 600. K and 3.5 X 10^-3 L/mol*s at 650. K.

Question

a) determine the activation energy for this reaction.
b) determine the rate constant at 700. K

Answer 1

a. ln(k2/k1) = Ea(1/T1 - 1/T2)/RT
b. After you have Ea, then use the same formula to determine the new k.
