When forward reaction and reverse reaction occur at the same time it is called
Correct answer: C. Chemical equilibrium
- A. Forward equilibrium
- B. Reverse equilibrium
- C. Chemical equilibrium
- D. None of above
Explanation
When the forward reaction and the reverse reaction occur at the same time and at the same rate, the system is in a state of dynamic equilibrium. At chemical equilibrium, the concentrations of reactants and products remain constant over time, but both reactions continue to occur. The rates of the forward and reverse reactions are equal, leading to no net change in the concentrations of the reactants and products.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
