Question

the rate at which substance reacts is directly proportional to the active masses the the reacting substance is directly proportional to the product of masses of the reacting substance
Did i write right

Answer 1

Answer:

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. According to the law of mass action, rate of reaction is proportional to active mass of the reactants.

Consider the general reaction nA+mB→product

Rate=k[A]
