Re: Solving for Arrhenius Equation
Maybe try to separate your calculations into solving for -Ea/RT first, then plug that answer into e^(answer). After that try multiplying your value by A, and you should end up with the right rate constant. k (rate constant) is highly dependent on Ea, the activation energy.
