In a reaction $2A + B \to {A_2}B$, the reactant $ A $ will disappear at

Rate constant for a reaction ${H_2} + {I_2} \to 2HI$ is $49$, then rate constant for reaction $2HI \to {H_2} + {I_2}$ is

For the reaction $A + B \to C$, it is found that doubling the concentration of $A$ increases the rate by $4$ times, and doubling the concentration of $B$ doubles the reaction rate. What is the overal order of the reaction.

In the following reaction $A \longrightarrow B + C$, rate constant is $0.001\, Ms^{-1}$. If we start with $1\, M$ of $A$ then concentration of $A$ and $B$ after $10\, minutes$ are respectively

Assuming the reaction

$2NO(g) + Cl_2(g) \longrightarrow 2NOCl(g)$

occurs in a single elementary step, we can say that

The following data are for the decomposition of ammonium nitrate in aqueous solution Volume of ....... The order of the reaction is
