How does temperature affect the rate constant?

increase in temperature causes an increase in the rate constant (because you T2 is larger so Ea/R(1/T1 - 1/T2) is positive therefore lnK2/k1 is positive.

Increasing temperature increases the energy of the atoms or molecules that are participating in a reaction, so it makes them collide more frequently and with higher energy. Because they collide more often and with higher energy, they overcome the activation energy barrier more often, so the reaction happens more, which increases the speed of the reaction, which increases the rate constant.
