Two systems, PCI(5(g)) harr PCI(3(g)) + ...

Two systems, `PCI_(5(g)) harr PCI_(3(g)) + Cl_(2(g))` and `COCl_(2(g)) harr CO_((g)) + Cl_(2(g))` are simultaneously in equilibrium in a vessel at constant volume. If some CO is introduced into the vessel, then at the new equilibrium, the concentration of:

A

`PCL_5` is greater than that before

B

`PCL_3` is greater than that before

C

`PCL_5` is less than that before

D

`COCL_2` is more than that before

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
CO is added 2nd equilibrium shifts left `:. COCl_(2)` is more than before `Cl_(2)` is reduced, `:.` 1st equation shift to the right `:. PCl_(5)` will decrease
