Question

Theory of active mass indicates that the rate of chemical reaction is directly proportional to the

• A. Equilibrium constant
• B. Properties of reactants
• C. Volume of apparatus
• D. Concentration of reactants

Answer 1

The correct option is D Concentration of reactants

The rate of chemical change is directly proportional to product of active masses at that temperature. In fact, the rate of a reaction is defined as the change in concentration (number of moles per litre) of reactants or products per unit time.
(d) is correct.
