A is the pre-exponential or frequency factor which essentially gives you the proportion of reactants that collide in the correct orientation and with enough energy in order to form products.

A is the frequency factor for the reaction. It is specific to each reaction.

### Re: Arrhenius Equation

Can we assume A will be 1 unless the question specifies that we have to solve for it?
