Part A For the reaction 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 K = K (RT)An where R=0.08206 L-atın/K mol). T is the absolute temperature, and An is the change in the number of moles of gas (sum moles products - sum moles reactants). For example, consider the reaction N (g)...
