Problem

The data given below are for the reaction of

\text{NO}

and

\text{Cl}_2

to form

\text{NOCl}

295 \text{ K}

$[\text{Cl}_2]$	$[\text{NO}]$	Initial rate ( $\text{mol litre}^{-1}\text{sec}^{-1}$ )
0.05	0.05	$1 \times 10^{-3}$
0.15	0.05	$3 \times 10^{-3}$
0.05	0.15	$9 \times 10^{-3}$

(Roorkhee 1993) (a) What is the order with respect to

\text{NO}

and

\text{Cl}_2

in the reaction? (b) Write the rate expression. (c) Calculate the rate constant. (d) Determine the reaction rate when conc. of

\text{Cl}_2

and

\text{NO}

are

0.2 M

and

0.4 M

respectively.
