The balanced reaction between nitrogen and hydrogen to form ammoinia is as shown.

N2 + 3H2=2NH3

Dividing everything by 3

1/3N2 + H2 = 2/3NH3

All the hydrogen reacts with 1/3 of 0.5 atm of N2

The amount of product is 2/3 * 0.6 atm = 0.4 atm NH3

The unreacted nitrogen is 2/3 * 0.6 atm = 0.4 atm Nitrogen

That adds up to 0.8 atm
