Medium· Temperature Dependence of the Rate of a Reaction (Arrhenius Equation)· +4 / −1

For an elementary chemical reaction, the Arrhenius plot is given below. Figure: a plot of

\ln k

(vertical axis, marked

2, 4, 6, 8

) against

1/T

(horizontal axis). It is a straight line with a negative slope that cuts the

\ln k

axis at

\ln k = 6

.
