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) | $1.0$ | $0.75$ | $0.40$ | $0.10$ |
$\mathrm{t}$ (min.) | $0.0$ | $0.05$ | $0.12$ | $0.18$ |
The order of the reaction is
$1$
$0$
$2$
$3$
Write differential rate expression of following reaction and give its order of reaction :
$5 B r^{-}+B r O_{3}^-+6 H^{+} \rightarrow 3 B r_{2}+3 H_{2} O$
The reaction $2{N_2}{O_5}$ $\rightleftharpoons$ $2N{O_2} + {O_2}$ follows first order kinetics. Hence, the molecularity of the reaction is
Order of a reaction is decided by
A student has studied the decomposition of a gas $AB _3$ at $25^{\circ} C$. He obtained the following data.
$p ( mm Hg )$ | $50$ | $100$ | $200$ | $400$ |
Relative $t _{1 / 2}( s )$ | $4$ | $2$ | $1$ | $0.5$ |
The order of the reaction is
The order of a reaction is said to be $ 2 $ with respect to a reactant $X, $ when
