A reaction has a rate constant of 1.23×10-4 s at 28 degrees C and 0.235 s at 79 degrees C.

A: Determine the activation barrier for the reaction.

B: What is the value of the rate constant at 15 degrees C?

I know that I need to use the Arrhenius formula. However, I am not sure which values go where. If someone could please show me, I would greatly appreciate it.
