In some cases,the reaction rate increases with time. This phenomenon is known as ..........

What is chemical kinetics? Which information is obtained by chemical kinetics and thermodynamics regarding a reaction?

In the following reaction,$2H_2O_2 \to 2H_2O + O_2$,the rate of formation of $O_2$ is $36 \ g \ min^{-1}$. What is the rate of disappearance of $H_2O_2$ in $mol \ min^{-1}$?

For the chemical reaction $N_2 + 3H_2 \rightarrow 2NH_3$,the rate of reaction can be expressed in terms of the derivatives of the concentrations of $N_2$,$H_2$,or $NH_3$. Write the correct relationship between the rate expressions.

For the reaction,$3 I_{(aq)}^{-} + S_2 O_{8_{(aq)}}^{2-} \longrightarrow I_{3_{(aq)}}^{-} + 2 SO_{4_{(aq)}}^{2-}$,the rate of formation of $SO_4^{2-}$ is $0.022 \ mol \ dm^{-3} \ sec^{-1}$. What is the rate of formation of $I_{3_{(aq)}}^{-}$?

In a pseudo first order reaction in water,the following results were obtained:

$t / s$	$0$	$30$	$60$	$90$
$[A] / mol \ L^{-1}$	$0.55$	$0.31$	$0.17$	$0.085$

Calculate the average rate of reaction between the time interval $30$ to $60 \ s$.
