Question

In _____, the forward and reverse reactions take place at the same rate. A. activated complexes B. chemical equilibrium C. elementary reactions D. first-order reactions

Answer 1

B. chemical equilibrium

Answer 2

Answer:

The correct answer is option B

Explanation:

Characteristics of chemical equilibrium:

• It is attained is closed system.
• The macroscopic constraint remain constant like: volume, pressure, energy etc.
• Rate of forward reaction is equal to the rate of backward reaction.
• The concentration of the reactants and products remain constant.They are not always equal.

Hence, the correct answer is option B
