The synthesis of NH3 is represented by the equation above. based on the equilibrium constant, K and delta H rxn given above, which of the following can best be used to justify that the reaction is thermodynamically favorable at 298 K and constant pressure? N2 (g) + 3H2 (g) --> 2NH3 (g)
K= 5.6 × 10^5 at 298 K
delta H rxn= -91.8 kj/mol
