The air pollutant NO is produced in automobile engines from the high-temperature reaction:
N2(g)+O2(g)â2NO(g) Kc=1.7Ã10â3at 2300 K.

Part A

Calculate the equilibrium concentration of [N2] if the initial concentrations are 2.27 M N2 and 0.58M O2. (This N2/O2 concentration ratio is the ratio found in air.)

Part B

Calculate the equilibrium concentration of [O2].

Part C

Calculate the equilibrium concentration of [NO].

If KC = 6.4x10^â7 for the reaction system 2CO₂(g) â 2 CO(g) + O₂(g)
state whether each of the following mixtures is at equilibrium. Ifthe mixture is not at equilibrium, tell whether the reaction willshift to the left (favor reactant) or to the right (favor product)to reach equilibrium.
(a) [CO₂] = 5.3x10^â2 M; [CO] =3.6x10^â4 M; [O₂] = 2.4x10^â3 M

(b) [CO2] = 1.47x10^â2 M; [CO] = 3.8x10^â3M; [O₂] = 6.5x10^â4 M
