### Arrhenius Equation A variable

Will we be given what the value for A is for the Arrhenius equation? I don't know how else you could solve for k without knowing it.

The value of A would be given. We would not be expected to find A in order to use the Arrhenius equation.

This equation can also be modified and used in order to compare the rate constants at two different temperatures. The modified equation would be ln(k2/k1) = (Ea/R)(1/T2 - 1/T1).

Since A must be solved for experimentally, I don't think we will have to know how to find it.
