A sphere of 10L is filled with a mixture consisting of 25% NO and the rest dry air at 20C and 1 atm. We allow equilibrium to be reached.

Determine:

a. The total final pressure and the partial pressure of the species in the equilibrium.

b. The total final pressure and the partial pressure of the species in the equilibrium if the temperature becomes 10C or 40C (A.F. Tena).
