Why does the rate of any reaction generally decreases during the course of the reaction?

Options

  1. AThe concentration of reactants increases as the reaction progresses.
  2. BThe rate of a reaction depends on the concentration of reactants. As the reaction progresses, reactants start
  3. CThe rate of product formation is independent of the reaction progress.
  4. DAs the reaction progresses, the concentration of reactants decreases.

Correct answer

B. The rate of a reaction depends on the concentration of reactants. As the reaction progresses, reactants start

Step-by-step solution

Correct Option is : (B) The rate of a reaction depends on the concentration of reactants. As the reaction progresses, reactants start getting converted to products so the concentration of reactants decreases hence the rate decreases.
