6. Theory of ‘active mass’ indicates that the rate of chemical reaction is directly proportional to the [MP PET 1990] (a) Equilibrium constant (b) Properties of reactants (c) Volume of apparatus (d) Concentration of reactants
Correct option is D) 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
