The reaction quotient Q determines the direction a reaction must go to get to equilibrium. N2(g) + O2(g) - 2 NO(g) For the above reaction if we start with only N2 and O2 the reaction must go the right of make NO. If we start with only NO the reaction must go to the left to make N2 and O2. To find the direction of change first find the reaction quotient Q. Find Q by plugging the initial reaction concentrations into the equilibrium expression. If Q less than K the reaction goes to the right If Q more than K the reaction goes to the left If Q = K the system is at equilibrium
