Question

A system at equilibrium contains I2(*g*) at a pressure of
0.23 atm and I(*g*) at a pressure of 0.24 atm . The system
is then compressed to half its volume.

Find the pressure of I2 when the system returns to equilibrium.

Express your answer to two significant figures and include the appropriate units.

Find the pressure of I when the system returns to equilibrium.

Answer #1

When volume is reduced to one half, the partial pressures of each species are doubled.

Then let x atm of I2 decompose to reach equilibrium., They will form 2x atm of I.

The equilibrium partial pressure of I will be

The equilibrium pressure of I2 will be

The expression for the equilibrium constant is

On solving the above equation, we get, x = -0.48 or x = -0.0598.

The value -0.48 is neglected as 0.48+2x will be a negative quantity.

Hence, the equilibrium pressure of I2 is

The equilibrium pressure of I is
