You should use the Arrhenius Equation when determining the effect of a change in temperature on the rate constant

Also when you are looking at activation energy

When you want to know the effect on K with the change in temperature

it's useful in situations where you want to see how the rate, temperature, and activation energy all relate

And the ln(k) = -Ea/RT + ln(A) version is useful when you're comparing two temperature's k values. The equation becomes ln(k2/k1) = (Ea/R)((1/T1) - (1/T2))
