314825 Assertion :
The degree of decomposition of \(\mathrm{PCl}_{5}\) is more at low pressures.
Reason :
In a reversible reaction, on increasing the pressure the equilibrium shifts in the direction in which decrease in volume takes place.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
