Q40 / 180 · COMEDK 2019 · Chemistry

Just before attaining the chemical equilibrium

  • Correct answer
    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.

Solution

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.

Hence, the correct answer is option: 'A'.
