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)Δn
where R=0.08206L⋅atm/(K⋅mol), T is the absolute temperature, and Δn is the change in the number of moles of gas (sum moles products - sum moles reactants). For example, consider the reaction
N2(g)+3H2(g)?2NH3(g)
for which Δn=2-(1+3)=-2.v
1A.
For the reaction
2A(g)+3B(g)?C(g)
Kc = 79.2 at a temperature of 289 °C .
Calculate the value of Kp.
Express your answer numerically.
1B.
For the reaction
X(g)+3Y(g)?3Z(g)
Kp = 3.37×10-2 at a temperature of 231 °C .
Calculate the value of Kc.
Express your answer numerically.
