Which factor will shift the following equilibrium in forward direction ?
`AgCl(s) rarr Ag^(+)(aq) + Cl^(-)(aq)`

A

Addition of `NH_(3)(aq)`

B

Addition of `AgNO_(3)(aq)`

C

Addition of NaCl(aq)

D

Addition of AgCl(s)

Text Solution

Verified by Experts

The correct Answer is:
A
`CO_(2)(g) + C(s) rarr 2CO(g)`
This is case of heterogeneous equilibrium.C(s) being solid is not considered.Total pressure of `CO_(2)` and CO gases.
`P_(CO_(2)) + P_(CO) = P_(total)`
`0.5-p+2p = 0.8`
P = 0.3 atm
`P_(CO_(2)) = 0.5 - 0.3 = 0.2 atm`
`P_(CO) = 2p = 0.6 atm`
`K_(p) = P^(2)_(CO)/P_(CO_(2)) = (0.6 xx 0.6 )/0.2 = 1.8 atm`
