Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Le Chatelier's Principle

Le Chatelier's Principle states that if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change. This means that if a reactant or product is added or removed, the system will adjust to restore equilibrium, either by shifting to the left (toward reactants) or to the right (toward products).

Equilibrium Constant (K)

The equilibrium constant (K) is a numerical value that expresses the ratio of the concentrations of products to reactants at equilibrium for a given reaction at a specific temperature. It provides insight into the extent of the reaction and helps predict the direction of the shift when the system is disturbed. A change in concentration of reactants or products can affect the value of K.

Reaction Quotient (Q)

The reaction quotient (Q) is a measure of the relative concentrations of products and reactants at any point in time, not just at equilibrium. By comparing Q to K, one can determine the direction in which the reaction will shift to reach equilibrium. If Q < K, the reaction will shift to the right; if Q > K, it will shift to the left.
