### 15.63

The solution states that ln(k’/k)=Ea/R*(1/298K - 1/310K) - 0.59.
What is the significance of the -0.59? Someone previously explained that it is mathematically equivalent to ln(k1/k2) but what is the meaning of it? And why is it being subtracted from the rest of the equation?

### Re: 15.63

Why isn't it ln(k2, k1)=Ea/R((1/T1)-(1/T2)? Thats what I used and got the same answer as the solutions manual.
