The reversible reaction has reached equilibrium when the forward reaction occurs at a rate (blank) to the reverse reaction rate and the concentrations of the reactants and products stay constant.
When molecules start to react in a reversible reaction, the forward reaction occurs at a faster rate than the reverse reaction.
As more products are formed and reactants are consumed, the relative rate of the forward reaction slows down and the relative rate of the reverse reaction speeds up.
The reversible reaction has reached equilibrium when the forward reaction occurs at a rate equal to the reverse reaction rate and the concentrations of the reactants and products stay constant.

When molecules start to react in a reversible reaction, the forward reaction occurs at a (faster rate than) the reverse reaction.
As more products are formed and reactants are consumed, the relative rate of the forward reaction (slows down) and the relative rate of the reverse reaction (speeds up).
The reversible reaction has reached equilibrium when the forward reaction occurs at a rate (equal) to the reverse reaction rate and the concentrations of the reactants and products stay constant.
Explanation:
In a reversible reaction, the forward reaction occurs initially at a faster rate than the reverse reaction because there are more reactant molecules available for the forward reaction. As the forward reaction progresses and more products are formed, the concentration of reactants decreases, leading to a slower rate of the forward reaction. At the same time, the concentration of products increases, allowing for more frequent collisions and a faster rate of the reverse reaction. Eventually, the rates of the forward and reverse reactions become equal, and the system has reached equilibrium, where the concentrations of reactants and products remain constant.
