Questions & Step-by-Step Solutions
Which of the following statements is true about a system at equilibrium?
Step 1: Understand what equilibrium means in a chemical reaction. It is a state where the reaction does not change over time.
Step 2: Recognize that at equilibrium, the forward reaction (reactants turning into products) and the reverse reaction (products turning back into reactants) are happening at the same rate.
Step 3: Note that while the rates of the reactions are equal, the actual amounts (concentrations) of reactants and products do not have to be the same.
Step 4: Conclude that the true statement about a system at equilibrium is that the rates of the forward and reverse reactions are equal.
