Under a goven set of experimental conditions, with increase in the concentration of the reactants, the rate of a chemical reaction

Answer»

Decreases
Increases
Remains unaltered
First decreases and them increases

Solution :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".
