Detailed explanation-1: -The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. Reaction rates can vary dramatically.

Detailed explanation-2: -The rate of a chemical reaction is defined as the rate of change in concentration of a reactant or product divided by its coefficient from the balanced equation.

Detailed explanation-3: -reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

Detailed explanation-4: -The speed of a reaction is given by the reaction rate, a measure of how fast reactants are consumed and products are formed. The study of reaction rates is known as chemical kinetics. The central theory of kinetics is collision theory. The premise of this theory is simple: molecules have to collide to react.

Detailed explanation-5: -Chemical kinetics is the study of the rates of chemical reactions or how fast reactions occur. The primary requirement for a reaction to occur is that the reactant particles (atoms or molecules) must collide and interact with each other in some way.
