### Equation

With ln k2/k1 =Ea/R (1/T - 1/T2) is it assumed that A is 1?

### Re: Equation

Yeah I believe for our purpose we are usually assuming A is just 1.

### Re: Equation

I think we should assume A is 1 unless otherwise stated

### Re: Equation

I thought for that equation that A ends up getting canceled out during the derivation and that's why it isn't present

Yes, we should assume A=1 unless they tell us otherwise.

### Re: Equation

Correct, if we assume A=1, it should cancel out in the derivation for this condition.
