Part B Review I Constants I Periodic Table
When a chemical reaction is at equilibrium, $Q$ (the reaction quotient) is equal to $K$ (the equilibrium constant). If a stress is applied to the mixture that changes the value of $Q$ , then the system is no longer at equilibrium. To regain equilibrium, the reaction will either proceed forward or in reverse until $Q$ is equal to $K$ once again. Alternatively, equilibrium can be disrupted by a change in temperature, which changes the value of $K$ . The result however is the same, and the reaction will proceed forward or in reverse until $Q$ is equal to the new $K$ . Le Châtelier's principle summarizes this idea:
If a stress is applied to a reaction mixture at equilibrium, a net reaction occurs in the direction that relieves the stress. - The following system is at equilibrium: $\mathrm{A}(\mathrm{s})+4 \mathrm{~B}(\mathrm{~g}) \rightleftharpoons \mathrm{C}(\mathrm{g})$ Classify each of the following actions by whether it causes a leftward shift, a rightward shift, or no shift in the direction no shift in the direction of the net reaction.
