Given the following experimental data at a given temperature:

     2 NO(g) ⇌  N₂(g) + O₂(g)           K₁ = 2.67 x 10¹⁰           ∆H₁ = -180.2 kJ/mol

     2 NO(g) + O₂(g) ⇌ 2 NO₂(g)      K₂ = 5.38 x 10¹⁵           ∆H₂ = -112.3 kJ/mol

     

     For a and b consider following reactions:

           

            N₂(g) + 2 O₂(g) ⇌ 2 NO₂(g)

           

• a. Determine the equilibrium constant, K at this same temperature                

• b. Determine ∆H at this same temperature for one of the above reactions.
