Simple answer: When a reaction occur change in the concentrations of reactants or products per unit of time is called reaction rate .
Scientific answer: The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. for example, the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years, but combustion of cellulose in a fire is a reaction that takes place in fractions of a second.
Reaction rate is a measure of how quickly a chemical reaction occurs. It can be quantified by the rate at which reactants are consumed or products are produced over time. Factors such as temperature, concentration of reactants, and presence of catalysts can influence the reaction rate.
Rate of reaction is the speed at which a chemical reaction is taking place. Reactions do not progress at a constant speed (usually). The rate is generally dependent on the amount of one or more reactants remaining in the system.

What does the rate law use to determine the rate of a reaction?
The rate law uses the concentrations of reactants to determine the rate of a reaction. By experimentally determining the relationship between the rate of reaction and the concentrations of reactants, we can derive the rate law equation for that specific reaction.
What does the rate law use to determine the rate of reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What effect does the concentration of reactants have on the the rate of a reaction?
The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
What does the rate of law use to determine the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What is necessary to determine the rate of a reaction using the rate law?
To determine the rate of a reaction using the rate law, you need to know the rate constant (k), the concentrations of the reactants, and the order of the reaction with respect to each reactant. The rate law equation relates the rate of the reaction to these factors.
Define chemical kinectics and it components?
Chemical kinetics is the study of the rates at which chemical reactions occur and the factors that influence these rates. Its components include the rate of reaction, activation energy, reaction mechanisms, and reaction orders. By understanding these components, chemists can predict and control the speed of chemical reactions.
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.

What does the reaction rate indicate about a particular chemical reaction?
The reaction rate indicates how quickly the reactants are being converted into products in a chemical reaction. A faster reaction rate means the reaction is proceeding more rapidly, while a slower reaction rate indicates the reaction is proceeding more slowly.
What can change the rate of reaction of enzymes?
Heat can change the rate of reaction
What happens after equilibrium?
Rate of forward reaction=rate of backward reaction
