Question

For the Equilibrium System

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

1.) Write a Kc and a Kp expression.

2.) If Kc = 1.50 x 10^-2 at 653^oC, Calculate and report the equilibrium concentrations of all of the reactants and all of the products at 653^oC, if the initial concentrations were

[N₂]₀ = 0.0100 M

[O₂]₀ = 0.0200 M

[NO]₀ = 0.00300 M

3.) Calculate Kp for this equilibrium system at 653^oC using the equation Kp = Kc(RT)^∆n.

N.B., you will have to do ALL of the following in order to receive full credit . . .

i.) calculate a value for Q to determine whether the system is already at equilibrium OR which direction it will have to proceed in order to achieve equilibrium;

ii.) construct an I-C-E Table and fill it in completely;

iii.) show an adequate number of detailed steps in your calculations so that I can follow your logic from start-to-finish; and

iv.) report your numerical answers to the correct number of sig. figs. and then “box” them.
