Paper 2 · chemical equilibrium

For the equilibrium N2(g)+3H2(g)2NH3(g)N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g), the expression for KpK_p is

ApNH32pN2pH23\frac{p_{NH_3}^2}{p_{N_2}\,p_{H_2}^3}
BpN2pH23pNH32\frac{p_{N_2}\,p_{H_2}^3}{p_{NH_3}^2}
CpNH3pN2pH2\frac{p_{NH_3}}{p_{N_2}\,p_{H_2}}
D2pNH3pN2+3pH2\frac{2p_{NH_3}}{p_{N_2} + 3p_{H_2}}
Explanation: Partial pressures of the products go on top, each raised to the power of its coefficient in the equation.
