the reaction?


NCERT Class XII
Chemistry - Exemplar Problems

Chapter 4. Chemical Kinetics

Answer 1

the rate of the reaction depends upon the conc. of the reactants.as the reaction proceeds in forward direction,conc.of  reactants decreases and that of products increases,so............

Answer 2

Hey !!

The rate of 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 of reaction decreases.
