Question

The temperature dependence of the rate of a chemical reaction is given by Arrhenius equation, $k=Ae^{-E_{a} /RT }\cdot$Which of the following graphs will be a straight line?

• A. In $A \,vs$ $1 /T$
• B. In $A \,vs$ $E_a$
• C. In $k\, vs$ $1 /T$
• D. In $k \,vs$ $-E_a/R$

Answer 1

Answer: (C)

The plot of In $k \,vs \,1/T$ gives a straight line according to the equation,
In $k=-\frac{E_{a}}{RT}+ln\, A$
