Reference: AQA
Equilibrium is reached when the forward and reverse reactions occur at exactly the same rate, so both reactions continue but the amounts of reactants and products remain constant.
A new equilibrium is established in which the forward and reverse reaction rates become equal again, and both reactions continue.
The state reached when the rates of the forward and reverse reactions become equal again.
A state in which both forward and reverse reactions continue at equal rates.
The point in a reversible reaction in a closed system where the rate of the forward reaction equals the rate of the reverse reaction, and the concentrations of reactants and products remain constant.
The point in a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction, and the concentrations of reactants and products remain constant.
