Just before attaining the chemical equilibrium
- A rate of forward reaction decreases and rate of backward reaction increases
- B rate of forward reaction increases and rate of backward reaction decreases
- C no change in the rates of forward and backward reactions.
- D rate of forward reaction equals the rate backward reaction.
Answer & Solution
Correct Answer
(A) rate of forward reaction decreases and rate of backward reaction increases
Step-by-step Solution
Detailed explanation
Just before attaining chemical equilibrium rate of forward reaction decrease and rate of backward reaction increases. As the concentration of product is slightly more than the equilibrium concentration.
