A chemical reaction has reached to a state of dynamic equilibrium at a certain temperature. Which of the following statements is incorrect?
Correct answer: C. The rate of forward and backward reactions are the same
- A. The concentration of the reactants remains constant
- B. Products are continuously being formed
- C. The rate of forward and backward reactions are the same
- D. The reaction has stopped completely
Explanation
At dynamic equlibrium state, the reaction does not stops. Foraward and reverse reaction keep on taking place in opposite direction.

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.
