Answer :
Answer: Option (3) is the correct answer.
Explanation:
A reaction in which the concentration of reactants equal to the concentration of products is known as an equilibrium reaction.
For example, [tex]Ca(OH)_{2}(s) + H_{2}O(l) \rightleftharpoons Ca^{2+}(aq) + 2OH^{-}(aq)[/tex]
Therefore, we can also say that in an equilibrium reaction rate of forward reaction becomes equal to the backward reaction.
The true statement about a system at equilibrium is that the forward reaction rate is equal to the reverse reaction rate.
What is equilibrium state?
Equilibrium state is that state in which the concentration of reactant as well as of producrs are constant. i.e. not changes.
Equilibrium state of any reaction will be represented by the double headed arrow as:
A + B ⇄ C + D
Given reaction defines that rate of forward reaction is equal to the rate of the backward reaction.
Hence option (3) is correct.
