What is the effect of increasing pressure on the dissociation of `PCl_5`, according to the equation `PCl_(5(g)) hArrPCl_(3(g)) + Cl_(2(g)) - x` cal

A

Dissociation decreases

B

Dissociation increases

C

Dissociation does not change

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

`PCl_(5(g)) hArr PCl_(3(g)) + Cl_(2(g))`
For this reaction `Deltan = 2 -1 = 1`
Value of `Deltan` is positive so the dissociation of `PCl_5` take forward by decrease in pressure & by increase in pressure the dissociation of `PCl_5` decrease.
