Identify the order of the following reaction:
$2H_2O_{2(aq)} \longrightarrow 2H_2O_{(l)} + O_{2(g)}$

Consider the following reactions:
$A$ $\rightarrow P_1; B$ $\rightarrow P_2; C$ $\rightarrow P_3; D$ $\rightarrow P_4$
The orders of the above reactions are $a, b, c,$ and $d,$ respectively. The following graph is obtained when $\log[\text{rate}]$ vs. $\log[\text{conc.}]$ are plotted:
Among the following,the correct sequence for the order of the reactions is:

Explain the order of reaction for complex reactions by giving examples.

The given reaction $2NO + O_2 \to 2NO_2$ is an example of

Under a given set of experimental conditions,with an increase in the concentration of the reactants,the rate of a chemical reaction

For a reaction $2 \ A + B \rightarrow P$, when the concentration of $B$ alone is doubled, the rate does not change, and when the concentrations of both $A$ and $B$ are doubled, the rate increases by a factor of $4$. The unit of the rate constant is,
