Question
What is the equilibrium mole fractions of ammonia, nitrogen, and hydrogen at 1 bar and 300 K?
The mole fractions are
yN2 is____
yH2 is ____
yNH3 is _____
![For the ammonia synthesis reaction,
N2(9) + 3H2(g) – 2NH3(g)
the equilibrium conversion to ammonia is large at 300 K but decreases rapidly with increasing T.
However, reaction rates become appreciable only at higher temperatures. For a feed mixture of
hydrogen and nitrogen in the stoichiometric proportions, determine the following: (Take the value
of R to be 8.314 J-mol-1.K-1. For data, use the heat capacities of gases in the ideal-gas state table and
the enthalpy and Gibbs energy of formation of the species table.)
