Explanation / Answer
to calculate the Activation Energy by graphing lnk versus 1/T. When the lnk (rate constant) is plotted versus the inverse of the temperature (kelvin), the slope is a straight line. The value of the slope (m) is equal to -Ea/R where R is a constant equal to 8.314 J/mol-K.
So here Ea = R* 6077 J/mol
6077 *8.314 J/mol = 50,524.178 J/mol
