When Cl 2 gas...

Question

When $C l_{2}$ gas is bubbled through concentrated and hot $K O H$ a firework explosive (A) is formed along with $K C l$ and $H_{2} O$ . How many grams of (A) will be formed by 150 L of $C l_{2}$ whose pressure is 950 mm of Hg at $27^{o} C$ ?
(take $R = \frac{1}{12} L a t m m o l^{- 1} K^{- 1})$

Solution

$3 C l_{2} + 6 K O H (a q .) \to K C l O_{3} (A) + 5 K C l + 3 H_{2} O$
We know that,
PV=nRT
$P = \frac{950}{760} a t m, V = 150 L$
$R = \frac{1}{12} L a t m K^{- 1} m o l^{- 1}, T = 300 K$
$n = \frac{P V}{R T} = \frac{950 a t m \times 150 L}{760 \times \frac{1}{12} L a t m K^{- 1} m o l^{- 1} \times 300 K}$
=7.5 mol
No.of moles of $K C l O_{3}$ produced = $\frac{1}{3} \times n o . o f m o l e s o f C l_{2}$
$= \frac{1}{3} \times 7.5$
$= 2.5 m o l$
Mass of $K C l O_{3}$ formed= $2.5 m o l \times 122.5 g / m o l$
=306.25 g
