Under a given set of experiemental condition, with increase in the concentration of the reactants, the reate of a chemical reaction

Options

A. Decreases
B. Increases
C. Remains unaltered
D. First decreases and them increases

Answer

B

Explanation

According to law of mass-action, "at a given temperature, the rate of a reaction at a particular instant is proportional to the product of the active masses of the reactants at that instant raised to powers which are numerically equal to the number of their respective molecules in the stoichiometric equation describing the reaction".
