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

From the rate expression for the following reactions, determine their order of reaction and the dimensions of the rate constants.

$(ii)$ $H _{2} O _{2}( aq )+3 I ^{-}( aq )+2 H ^{+} \rightarrow 2 H _{2} O ( l )+ I _{3}^{-} \quad$ Rate $=k\left[ H _{2} O _{2}\right][ I ]$

In the reaction, $A + B \to C + D$ , the rate $\left( {\frac{{dx}}{{dt}}} \right)$ when plotted against time $'t'$ gives a straight line parallel to time axis. The order and rate of reaction will be

Write about elementary and complex reactions.

The concentration of $R$ in the reaction $R \rightarrow P$ was measured as a function of time and the following data is obtained:

The order of the reaction is
