Question

How to find activation energy from slope and y intercept?

Answer 1

Kinetics Of A Reaction - Calculating Activation Energy. 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.
