Question

The reaction N2(g)+O2(g)2NO(g) is carried out at a different temperature at which Kc = 0.065. This time the reaction mixture starts with only the product, [NO] = 0.0100 M , and no reactants.

Part A Find the equilibrium concentration of N2 at equilibrium. Express your answer to two significant figures and include the appropriate units.

[N2] = _____ Units

Part B Find the equilibrium concentration of O2 at equilibrium. Express your answer to two significant figures and include the appropriate units.

[O2] = _____ Units

Part C Find the equilibrium concentration of NO at equilibrium. Express your answer to two significant figures and include the appropriate units.

[NO] = _____ Units

Explanation / Answer

N2(g)+O2(g)2NO(g)

kc = [NO]^2/[N2][O2]

0.065 = (0.01-2X)^2/(X^2)

X = 0.00443 M

[N2] = 0.0044 M

[O2] = 0.0044 M

[NO] at equilibrium = 0.01-0.00443*2 = 0.0011 M
