Examples:
1. Assume that the reaction for the formation of gaseous hydrogen iodide from hydrogen and iodine has an equilibrium constant of 2.3 x 102. In an experiment, 4.0 mol of each participant in the reaaction was added to a 2.0 L flask. Find the equilibrium concentrations of all species involved in this reaction.
The balanced equation for the reaction is: H2(g) + I2(g) <--> 2HI<sub>(g)
