Utterly Confused About Equilibria Problems

Equilibria problems require an equilibrium constant expression in nearly every case. You should begin each problem with this expression. This will get you started on the problem. 

Let s do a series of equilibria problems. You should pay close attention not only to what is different about each problem, but also to what is the same. 

The equilibrium mixture had an ammonia concentration of 0.120 M, a nitrogen concentration of 1.03 M, and a hydrogen concentration of 1.62 M. Determine the value of the equilibrium constant, Kc. 

A Temperatures often appear in equilibria problems, but most problems will not require you to use the temperature. 

The first step in this, and most equilibria problems, should begin by writing the equilibrium constant expression. In this case, the expression is
