Write differential rate expression of following reaction and give its order of reaction :

$H _{2} O _{2}+ I ^{-} \rightarrow H _{2} O + IO ^{-}$

$H _{2} O _{2}+ IO ^{-} \rightarrow H _{2} O + I ^{-}+ O _{2}$

The rate constant of esterification $(k) = k'\, [H_2O]$ rate constant of esterification $2.0\times 10^{-3}\,min^{-1}$ calculate  $k'$.

The specific rate constant of a first order reaction depends on the

The reaction, $X + 2Y + Z \to N$ occurs by the following mechanism

$(i)$ $X + Y \rightleftharpoons M$      very rapid equilibrium

$(ii)$ $M + Z \to P$      slow

$(iii)$ $O + Y \to N$      very fast

What is the rate law for this reaction

$n$ presence of $HCl$, sucrose gets hydrolysed into glucose and fructose. The concentration of sucrose was found to reduce form $0.4\,M $ to $0.2 \,M$  in $1$  hour and $0.1 \,M $ in $2$ hours. The order of the reaction is
