Arrhenius Equation

Science > Chemistry > Chemical Kinetics > Arrhenius Equation In this article, we shall study the factors affecting the rate of a chemical reaction and the Arrhenius equation. Factors Affecting the Rate Of Reaction: The Concentration of Reactants: The number of collisions and hence the activated collisions between the reactant molecules increase with the increase […]

Molecularity of Reaction and Catalysis

Science > Chemistry > Chemical Kinetics > Molecularity of Reaction and Catalysis In this article, we shall study the molecularity of reaction and catalysis. The Concept of Elementary Reactions: Many reactions that follow a simple rate law are actually taking place in series of steps. These reactions are called complex reactions. Each step in a […]

Applications of Adsorption

Science > Chemistry > Surface Chemistry > Applications of Adsorption In this article, we shall study some applications of adsorption. Adsorption Indicators: The phenomenon of adsorption is used to detect the endpoints of precipitation titrations. In such titrations, dyestuffs like eosin, fluorescein, alizarin red etc, are used as adsorption indicators. At the endpoint of the […]
