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.) NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
