Solution
Solution Steps
Step 1: Analyze Each Statement
Let's analyze each statement to determine its validity regarding chemical equilibrium.
This statement is incomplete and cannot be evaluated.
This statement is false. Reactions can reach equilibrium at various temperatures and pressures, not just standard conditions.
This statement is true. At equilibrium, the rates of the forward and reverse reactions are equal.
This statement is false. The equilibrium concentrations of reactants and products can change with temperature.
This statement is false. At equilibrium, the reactions have not stopped; they continue to occur, but at equal rates.
This statement is false. At equilibrium, the concentrations of reactants and products are not necessarily equal; they are constant but can be different.
Final Answer
The true statement about equilibrium is:
\(\boxed{\text{The rates of the forward and reverse reactions are equal.}}\)
