(Solved): Consider the reaction to form NH3 from its elemental constituents: 1/2N2(g)+3/2H2(g) ...
Consider the reaction to form NH3? from its elemental constituents: 1/2N2(g)?+3/2H2(g)??NH3(g)? If an initial mixture of 75.00% by volume H2? and 25.00% by volume N2? is allowed to come to equilibrium at 450?C and 300atm, the resulting equilibrium composition of 35.82%NH3(g)? by volume. Under these conditions, non-ideal effects must be considered. Recall that: f?PeRTB(T)P? Where: BH2?=16cm3/mol;BN2?=24.4cm3/mol;BNH3?=?31cm3/mol

?At equilibrium, the concentrations of the gases in the reaction can be determined from the volume percentages, using the total pressure of the system:
N2: (25.00/100) x (300 atm) = 75.0 atm
H2: (75.00/100) x (300 atm) = 225 atm
