For the reaction $2A + B \rightarrow 2C$,the rate of disappearance of $A$ is $0.076 \ mol \ s^{-1}$. What is the rate of disappearance of $B$?

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.

$NO_2$ required for a reaction is produced by the decomposition of $N_2O_5$ in $CCl_4$ as per the equation $2N_2O_{5(g)} \to 4NO_{2(g)} + O_{2(g)}$. The initial concentration of $N_2O_5$ is $3.00 \, mol \, L^{-1}$ and it is $2.75 \, mol \, L^{-1}$ after $30 \, minutes$. The rate of formation of $NO_2$ is ............... $mol \, L^{-1} \, min^{-1}$

Explain the difference between instantaneous rate of a reaction and average rate of a reaction.

In a pseudo first order hydrolysis of ester in water,the following results were obtained:

$t \ (s)$	$0$	$30$	$60$	$90$
$[\text{Ester}] \ (mol \ L^{-1})$	$0.55$	$0.31$	$0.17$	$0.085$

What will be the average rate of reaction between the time interval $30 \ s$ to $60 \ s$?

For the reaction,$A + 3 B \rightarrow 2 C$,the rate of consumption of $A$ is $1.4 \ mol \ dm^{-3} \ minute^{-1}$. Calculate the rate of consumption of $B$.
