Arrhenius Equation A (g) + B (g) C (g) The rate law for the above reaction is: -d[A]/dt = k [A][B] The rate constant is 2.9710 -6 L mol -1 s -1 at...

(i GOT THIS PART CORRECT)

PART B:- Calculate the rate constant k at 423.0°C for this reaction.?

PART C:-Calculate the pre-exponential factor A for this reaction.?

HOW TO SOLVE PART B (I GOT THE ANSWER 3.32*10^-6 BUT IT IS INCORRECT, I USED THE UNITS L/mol/s) and how to solve part C?
