Question

The equilibrium mixture, $S O_{3} (g) + N O (g) ⇌ S O_{2} (g) + N O_{2} (g)$ contains 0.6 mol of $S O_{3}$ , 0.4 mol of No, 0.8 mol of $S O_{2}$ and 0.1 mol of $N O_{2}$ per litre. If 1 mol of NO is introduced into the reaction vessel, then the number of moles of $S O_{3}, N O, S O_{2} a n d N O_{2}$ of each gas in the new equilibrium in moles per litre will be:

A

0.48, 1.3, 0.92 and 0.22

Solution

The correct option is A 0.48, 1.3, 0.92 and 0.22
$S O_{3} (g) + N O (g) ⇌ S O_{2} (g) + N O_{2} (g)$
No of moles 0.6 0.4 0.8 0.1
At equilibrium +1
1.4
Conc. Of reactant decreases, conc. of product increases according Le-Chatelier’s principle
