Chemical and Ionic Equilibrium - Result Question 32
####32. For the reaction, $PCl _5(g) \rightleftharpoons PCl _3(g)+Cl _2(g)$ the forward reaction at constant temperature is favoured by
(1991, 1M)
(a) introducing an inert gas at constant volume
(b) introducing chlorine gas at constant volume
(c) introducing an inert gas at constant pressure
(d) increasing the volume of the container
(e) introducing $PCl _5$ at constant volume
Show Answer
Solution:
- If inert gas is introduced at constant pressure, volume of container will have to be increased and this will favour the forward reaction. Also adding $PCl _5(g)$ at constant volume will favour forward reaction because $PCl _5(g)$ is a reactant.
