The rate constant for the reaction, $2{N_2}{O_5} \to 4N{O_2}$ $ + {O_2}$ is $3 \times {10^{ - 5}}{\sec ^{ - 1}}$. If the rate is $2.40 \times {10^{ - 5}}\,mol\,\,litr{e^{{\rm{ - 1}}}}{\sec ^{ - 1}}$. Then the concentration of ${N_2}{O_5}$ (in mol litre $^{-1}$) is
$1.4$
$1.2$
$0.04$
$0.8$
Which one of the following statements for the order of a reaction is incorrect?
$2 NO ( g )+ Cl _{2}( g ) \rightleftharpoons 2 NOCl ( s )$
This reaction was studied at $-10^{\circ} C$ and the following data was obtained
run | $[ NO ]_{0}$ | $\left[ Cl _{2}\right]_{0}$ | $r _{0}$ |
$1$ | $0.10$ | $0.10$ | $0.18$ |
$2$ | $0.10$ | $0.20$ | $0.35$ |
$3$ | $0.20$ | $0.20$ | $1.40$ |
$[ NO ]_{0}$ and $\left[ Cl _{2}\right]_{0}$ are the initial concentrations and $r _{0}$ is the initial reaction rate.
The overall order of the reaction is ..........
