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

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 $60 \ s$?

Consider the following reactant samples:
$I$. $1 \ mol$ of $A$ and $2 \ mol$ of $B$ in a $1 \ L$ vessel
$II$. $2 \ mol$ of $A$ and $2 \ mol$ of $B$ in a $2 \ L$ vessel
$III$. $0.2 \ mol$ of $A$ and $0.2 \ mol$ of $B$ in a $0.1 \ L$ vessel
Which reactant sample reacts at the highest rate if the reactants are in the gaseous state and do not follow a zero-order reaction?

Select the correct reaction for the given rate: $\text{rate} = -\frac{1}{6} \frac{d[A]}{dt} = -\frac{1}{4} \frac{d[B]}{dt} = \frac{1}{3} \frac{d[C]}{dt} = \frac{1}{4} \frac{d[D]}{dt}$

What is the rate of reaction?

For the reaction $I_2 + 2S_2O_3^{2-} \rightarrow 2I^{-} + S_4O_6^{2-}$,which of the following expressions correctly represents the rate of reaction?
