According to Arrhenius equation, k=Ae-Ea/RT textIn k = In A-( textE texta/ textRT) or log k= log A-(E/2.303RT) Hence, E is calculated with the help of slope.

Q. In terms of Arrhenius equation, $k = A e^{- E_{a} RT}$ the temperature dependence of rate constant (k) of a chemical reaction is written. Then, the activation energy $(E_{a})$ of the reaction can be calculated by plotting.

$log k vs \frac{1}{logT}$

$lo g k vs \frac{1}{T}$

$k vsT$

$k vs \frac{1}{l o g T}$

According to Arrhenius equation, $k = A e^{- E_{a} / RT}$ $In k = In A- \frac{E _{a}}{RT}$ or $lo g k = lo g A - \frac{E}{2.303 RT}$ Hence, E is calculated with the help of slope.
