Equilibrium describes the balance that results from a forward and reverse reaction proceeding at equal rates. Since reaction rat
es depend on concentration, temperature, and pressure, any changes in these conditions may alter the forward and reverse rates unequally and disrupt the equilibrium. Le Chatelier's principle states that after a change in conditions displaces a reaction from equilibrium
a) the reaction will undergo a temperature change in order to offset the disturbance.
b) the reaction proceeds to a new equilibrium in the direction that offsets the change.
c) the disturbance will always cause the forward reaction to be slower than the reverse reaction.
d) the change in conditions must be reversed in order to regain equilibrium.
b) the reaction proceeds to a new equilibrium in the direction that offsets the change.
Explanation:
According to Le Chatelier's principle, when a system experiences a constraint such as a change in pressure, temperature or concentration, the system will readjust itself in order to annul the constraint.
This simply means that when temperature, concentration or pressure is changed, a new equilibrium position is reached in order to offset the changes in the system.
