Rate of reaction and equilibrium

  1. A reaction begins with onlYits reactants and moves into the eventual equilibrium. Which of the
    following options is happening during the reaction until equilibrium is reached

The correct answer is C. May I know why the rate of forward reaction decreases?


i think rate of forward reaction will decrease because we will gradually have less and less reactant, i tried linking a graph but it wouldn’t work, look up “rate of reaction graph” you’ll see reactants go down and products go up

Hope this helps!
