A(g) + B(g) "> C(g)

The rate law for the above reaction is:

-d[A]/dt = k[A][B]

The rate constant is 2.84×10-3 L mol-1 s-1 at 335.0°C and 3.48×10-2 L mol-1 s-1 at 528.0°C.

Use the Arrhenius equation

k = Ae-Ea/RT

to:

Calculate Ea for this reaction.

Ea = (0.0821 L atm/ K mol x ln (3.48x10^-2/2.84x10^-3) ) / (1/608K - 1/ 801K) = 0.0821 L atm/mol x 2.5 / 0.00039 = 526.28 Latm/mol

Good Luck!
