The Arrhenius equation is written in the form,
This equation is of the form y = mx + C i.e., equation for a straight line. Thus, if a plot of log k is 1/T is a straight line, the validity of the equation is confirmed.
Thus the values of k at different temperatures are found and a plot of log k vs 1/T is made.
A straight line with a negative slope is obtained from the value of the slope, Ea can be calculated.
Slope = \(\frac{-E_a}{2.303 R}\)
