Document Summary
Rate of change of extent of reaction is the rate of reaction. Rate of reaction is positive for product and negative for reactant. Rate =1/b( [b]/ t) = -1/a ( [a]/ t) It goes on decreasing as the reaction progress due to decrease in the concentration(s) of the reactant(s). Unit of rate of reaction : mol l -1 s -1. The rate measured over a long time interval is called average rate and the rate measured for an infinitesimally small time interval is called instantaneous rate. In a chemical change, reactants and products are involved. As the chemical reaction proceeds, the concentration of the reactants decreases, i. e. , products are produced. The rate of reaction (average rate) is defined as the change of concentration of any one of its reactants (or products) per unit time. For reaction aa + bb + cc+ . It is the reaction which completes in a single step.
