Question

The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium constant, Kp, is calculated from partial pressures instead of concentrations. These two equilibrium constants are related by the equation

Kp=Kc(RT)%u0394n

where R=0.08206 L%u22C5atm/(K%u22C5mol), T is the absolute temperature, and %u0394n is the change in the number of moles of gas. For example, consider the reaction

N2(g)+3H2(g)%u21CC2NH3(g)

for which %u0394n=2%u2212(1+3)=%u22122.

1,

2A(g)+2B(g)%u21CCC(g)

Kc = 89.6 at a temperature of 135%u2218C .
