Question

For the reaction,
$P{Cl}_5\left(g\right)\rightleftharpoons P{Cl}_3\left(g\right)+{Cl}_2\left(g\right)$
The forward reaction at constant temperature is favoured by:

• A. introducing inert gas at constant volume
• B. introducing chlorine gas at constant volume
• C. introducing inert gas at constant pressure
• D. none of the above

Answer 1

Answer: (C)

introducing inert gas at constant pressure

For the reaction,
$P{Cl}_5\left(g\right)\rightleftharpoons P{Cl}_3\left(g\right)+{Cl}_2\left(g\right)$
The forward reaction at constant temperature is favoured by:
Introducing inert gas at constant pressure, introducing $P{Cl}_5$ gas, removing chlorine gas and removing $P{Cl}_3$ gas.
Note: Introducing inert gas at constant volume has no effect on equilibrium.
