k=A e-Ea / R T log k= log A-(Ea/2.303 R T) Comparing this equation with straight line y=m x+ c y= log k and x-(1/T) ∴ Ea is calculated with the help of slope by plotting the curve between log k and (1/T).

Q. The temperature dependence of rate constant $(k)$ of a chemical reaction is written in terms of Arrhenius equation $k = A e^{- E_{α} / RT}$ . Activation energy $(E_{a})$ of the reaction can be calculated by ploting

$lo g k v s T$

$lo g k v s \frac{1}{T}$

$k v s T$

$k v s \frac{1}{l o g T}$

$k = A e^{- E_{a} / RT}$
$lo g k = lo g A - \frac{E _{a}}{2.303 RT}$
Comparing this equation with straight line
$y = m x + c$
$y = lo g k$ and $x - \frac{1}{T}$
$∴ E_{a}$ is calculated with the help of slope by plotting the curve between $lo g k$ and $\frac{1}{T}$ .
