Rate of Reaction-Definition and Factors Affecting Reaction Rate, Formula, Average Rate of reaction, Instantaneous Rate of Reaction

August 22, 2025December 24, 2024 by Neeraj Anand, Param Anand
Rate of reaction refers to the speed at which the products are formed from the reactants in a chemical reaction. It gives some insight into the time frame under which a reaction can be completed. For example, the reaction rate of the combustion of cellulose in fire is very high and the reaction is completed in less than a second.

Integrated Rate Law Equation for Zero Order and First Order Reaction

December 24, 2024 by Neeraj Anand, Param Anand
An equation representing the dependence of the rate of reaction on the concentration of reacting species is known as a differential rate equation. The instantaneous rate of reaction is expressed as the slope of the tangent at any instant of time in the concentration-time graph. Hence, it is very difficult to determine the rate of reaction from the concentration-time graph. Therefore, we integrate the differential rate equation to obtain a relation between the concentration at different points and rate constant. This equation is known as the integrated rate equation. For reactions of different order, we observe different integrated rate equations.

Arrhenius Equation-Effect of Temperature on Rate of Reaction, FAQ’s

December 24, 2024 by Neeraj Anand, Param Anand
Temperature is one of the parameters that can affect the rate of a chemical reaction considerably. We have often seen milk boiling on a gas stove. The rate at which a specific quantity of milk boils depends on the flame of the stove. If the flame height is maximum, the milk boils in less time and if the flame height is minimum, the milk takes more time to boil. Here the flame height resembles temperature.

Chemical Kinetics MCQs with Answers Class 12 CBSE Chemistry Worksheet

December 24, 2024 by Neeraj Anand, Param Anand
Analytical chemistry uses reactions for the identification of chemical compounds. The chemical thermodynamics studies the chemical equilibrium as a source of work and heat etc. The kinetics also has its specific approach to the chemical reaction. It studies the chemical transformation as a process that occurs in time according to a certain mechanism with regularities characteristics of this process. The kinetics study in the chemical process is the study of reaction that occurs in time, it rates, a change in the rate with the development of the process.

August 22, 2025December 25, 2024 by Neeraj Anand, Param Anand
Rate of reaction or reaction rate in chemistry is defined as the speed or the rate at which a chemical reaction takes place. The rate of a chemical reaction is directly proportional to the increase in the concentration of a product per unit of time and to the decrease in the concentration of a reactant per unit of time. This can vary drastically. Chemical reactions proceed at extensively different speeds depending on the nature of the reacting substances, the type of chemical transformation, the temperature, and other factors.

Collision Theory & Activation Energy: Definition, Types, Example, and FAQs

December 25, 2024 by Neeraj Anand, Param Anand
Collision theory says that when particles collide (strike) each other, a chemical reaction occurs. However, this is necessary but may not be a sufficient condition for the chemical reaction. The collision of molecules must be sufficient to produce the desired products following the chemical reaction. The effective collision process, on the other hand, will determine the qualities and properties of the resulting product. As a result, understanding the collision theory is required in order to understand and determine the resulting products.

Activation Energy Formula, Derivation, Effect of Temperature on Rate Constant, Solved Problems

December 25, 2024 by Neeraj Anand, Param Anand
Activation energy of a chemical reaction is defined as the least amount of energy necessary to initiate the reaction. It can be interpreted as the differential in energy content between molecules and atoms that causes it to be in an activation or transition-state configuration while the associated atoms and molecules stay in their initial configuration. It is known that to initiate a reaction, molecules must collide with other molecules and exchange kinetic energy or velocity. There will be no response if the collision does not occur or if the molecules do not have enough kinetic energy. This forms the basis for the concept of activation energy. Its standard unit of measurement is kilojoules per mole (kj/mol).

Temperature Dependence of the Rate of a Reaction-Arrhenius Equation, Threshold energy, Activation energy

December 25, 2024 by Neeraj Anand, Param Anand
The meal cooks slowly if the gas is kept at a low temperature while cooking. When we raise the temperature to its highest setting, however, the food cooks quickly. As a result, increasing the temperature increases the rate of a reaction. The arrhenius equation helps explain this rate-temperature relationship. Let’s have a look at this equation and see how it works.
