A first order reaction has an activation energy of 68.1 kJ/mol and a frequency factor (Arrhenius constant) of 1.48 x 1012 sec -1. Calculate the rate constant at 18°C.
K = A * exp(- Ea / RT)
I understand what to plug into this equation, but I keep getting the wrong answer. I calculate (- Ea / RT), press 2nd + LN, and multiply that by A. Am I doing something wrong?
I'd appreciate any help.
