Question

According to arrhenius equation, the slope of $\log\, k$ vs $\frac{1}{ T }$ plot is:

• A. $\frac{-E_{a}}{2.303 R}$
• B. $\frac{- E _{ a }}{2.303}$
• C. $\frac{- E _{ a }}{2.303 RT }$
• D. $\frac{E_{a}}{2.303 R T}$

Answer 1

Answer: (A)

Arrhenius equation is $k = Ae ^{- Ea / RT }$

on taking log on both sides,

we get, $\log\, k =\log\, A -\frac{ E _{ a }}{2.303 RT }$

When $\log\, K$ is plotted with $1 / T$, the slope of the reaction

will be $\frac{- E _{ a }}{2.303\, R }$ and intercept given by $\log\, A$
