Concept Introduction:
Equilibrium constant in terms of concentration
Le Chatelier’s principle: If equilibrium is disturbed by changing conditions, the system will moves the equilibrium to reverse the change.
Factor’s that effect chemical equilibria:
Concentration – Equilibrium will be affected by changing the concentration of reactant or product. If we increase the concentration of reactant system will try to reverse the change by favouring forward reaction and thus increase the concentration of products. Like wise adding products increase yield of reactants.
Temperature – When the temperature increases equilibrium will shift in the endothermic direction, in the direction that absorbs heat. When the temperature decreases equilibrium will shift in the exothermic direction, in the direction that releases heat.

Answer to Problem 56GQ
Yes, the fractions found are agree with principle.
Explanation of Solution
According to Le Chatelier’s principle: If an equilibrium is disturbed by changing conditions, the system will move the equilibrium to reverse the change.
If we increase the concentration of reactant, system will try to reverse the change by favouring forward reaction and thus increase the concentration of products. Like wise adding products increase yield of reactants.
