In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
Kinetics Of A Reaction - Calculating Activation Energy. The rate constant of a reaction can be expressed as. k = Ae-Ea/RT. which is called the Arrhenius equation. Taking the natural log of both sides of the Arrhenius equation gives. ln k = -Ea/R(1/T) + ln A. The equation above is of the form y = mx + b, where y = ln k, m = -Ea/RT, x = 1/T, and b = ln A. For a reaction whose rate constant obeys the Arrhenius equation, a plot of ln k vs 1/T gives a straight line and it's slope can be used to determine Ea.
