**DrBob222**, Sunday, October 3, 2010 at 11:14pminitial pressure NH3 = 0.7317 atm.

initial pressure H2 = 0 and N2 = 0

At equilibrium

N2 = x

H2 = 3x

NH3 = 0.7317 - 2x

Kp = 67,100 = pN2*pH2^3/pNH3^2

Substitute into Kp and solve for x, then convert to NH3, H2, N2.

Finally, pNH3 remaining (from above) to percent of original amount present.
