Solution

The correct option is C ln k = ln A $- E_{a} / R T$
As we know,
Arrhenius equation
$k = A e^{- E_{a} / R t}$
or ln k = ln A $- E_{a} / R T$

According to Arrhenius equation rate constant k is equal to $A . e^{- E_{a} / R T .}$

Which of the following options represents the graph of ln k vs $\frac{1}{T}$ ?

K = A e^{- E_{a} / R T}

k = A e^{- \frac{E_{a}}{R T}}

E_{a}

A ⟶ B

k_{1} = A_{1} e^{- {E a}_{1} / (R T)}

X ⟶ Y

k_{2} = A_{2} e^{- {E a}_{2} / (R T)}

A_{1} = 10^{8}, A_{2} = 10^{10}

{E a}_{1} = 600 c a l / m o l, {E a}_{2} = 1800 c a l / m o l

k_{1} = k_{2}

R = 2 c a l / k m o l

k = A e^{- E_{a} / R T}
