Question

For the reaction : $PC{l}_5\left(g\right)\to PC{l}_3\left(g\right)+C{l}_2\left(g\right)$ The forward reaction at constant temperature is favoured by

• 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 $PC{l}_5$ at constant volume

Answer 1

Answer: (C), (D), (E)

The correct options are
C introducing an inert gas at constant pressure
D increasing the volume of the container
E introducing $PC{l}_5$ at constant volume

$PC{l}_5\left(g\right)\to PC{l}_3\left(g\right)+C{l}_2\left(g\right)$
so reaction will go to forward direction by adding reactants and go to backward by adding products.
Also, increasing the volume of the container will take reaction to forward direction (higher no of molecules).
