Question

Statement 1: For a chemical reaction at initial stage rate of forward reaction $\left(r_f\right)$ is greater than rate of reversed reaction $\left(r_b\right)$
Statement 2: When $r_f=r_b,$ chemical reaction is at equilibrium.

• A. Statement 1 is true but statement 2 is wrong
• B. Statement 2 is true but statement 1 is wrong
• C. Both statement are true
• D. None of above statement are true

Answer 1

The correct option is C Both statement are true

At the start of the reaction , only reactant is present and it will start to reacts and gradually forms products , therefore in a chemical reaction at initial stage rate of forward reaction $r_f$ is greater than rate of reversed reaction $r_b$.
It will happen until reaction reach equilibrium and at equilibrium, $r_f=r_b$ that is the rate of forward reaction becomes equal to rate of backward reaction.
