Q. The concentration of $R$ in the reaction $R \rightarrow P$ was measured as a function of time and the following data is obtained:
[R] (molar) 1.0 0.75 0.40 0.10
t(min.) 0.0 0.05 0.12 0.18

The order of the reaction is______

Solution:

From two data, (for zero order kinetics)
$K _{I}=\frac{ x }{ t }=\frac{0.25}{0.05}=5$
$K _{ II }=\frac{ x }{ t }=\frac{0.60}{0.12}=5$
