Question

Two system PCl 5 ​ ( g ) ⇌ PCl 3 ​ ( g ) + Cl 2 ​ ( g ) and COCl ( g ) ⇌ CO ( g ) + Cl 2 ​ ( g ) are simultaneously in equilibrium in a vessel at constant volume. If some CO is introduced in the vessel, then at new equilibrium, the moles of :

TestHub · Accepted Answer

The introduction of CO shifts the second equilibrium, $COCl (g) ⇌ CO (g) + C l_{2} (g)$ , to the left, consuming $C l_{2}$ . This decrease in $C l_{2}$ concentration then shifts the first equilibrium, $PC l_{5} (g) ⇌ PC l_{3} (g) + C l_{2} (g)$ , to the right to produce more $C l_{2}$ . Consequently, the moles of $PC l_{5}$ decrease.

Final Answer: The final answer is C
