Chapter 18, Problem 52E

“The equilibrium constant expression for a given reaction depends on how the equilibrium equation is written.” Explain the meaning of that statement. You may, if you wish, use the equilibrium equation ${\text{N}}_2\left(\text{g}\right)+{\text{3 H}}_2\left(\text{g}\right)\rightleftharpoons {\text{2 NH}}_{\text{3}}\left(\text{g}\right)$ to illustrate your explanation.
