The equilibrium system of hydrogen, nitrogen, and ammonia can be written in several different ways:

The equilibrium constant, K_eq, for reaction 1 is 0.19 at 532 °C. Write the equilibrium constant expression and calculate K_eq for reactions 2 and 3 at the same temperature.

Strategy

First, write the equilibrium constant expression for each equation, then examine the concentration terms to determine the relationship between equilibrium expressions. Use these relationships to calculate the relationships between equilibrium constants.
