The Rate of a Chemical Reaction The rate of a chemical reaction can be defined as the amount of the reaction which occurs in unit time. The rate of a reaction is measured by choosing certain properties of the reaction which will indicate how far the reaction has gone, and whose magnitude can be observed … Read more

Motion Motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. The branch of physics which deals with the study of motion of material objects is called mechanics. Mechanics is divided into following branches. (i) Statics : Statics … Read more
Chemical kinetics Chemical kinetics is that branch of chemistry which deals with the study of the speeds or the rates of chemical reactions, the factors affecting the rates of the reactions and the mechanism by which the reactions proceed. It concerns itself with the measurement of rates of reactions proceeding under the given conditions of … Read more
Acid An acid is a substance which forms H+ ions as the only positive ion in aqueous solution. Examples:- Hydrochloric acid dissolved in water forms H+ and Cl– ions HCl —> H+ + Cl– Sulphuric acid dissolved in water forms H+ and SO42- ions H2SO4 —>2H+ + SO42- Nitric acid forms H+ and NO3– ions when dissolved in water … Read more
Chemical equilibrium Chemical equilibrium is a state in which the rates of the forward and reverse reactions are equal and the concentrations of the reactants and products remain constant. Equilibrium is a dynamic process i.e. the conversions of reactants to products and products to reactants are still going on, although there is no net change … Read more

The Dance of Supply and Demand: Understanding Market Price Dynamics The market price of a good or service is a fundamental concept in economics, reflecting the dynamic interplay between supply and demand. It acts as a signal, guiding producers and consumers in their decision-making processes, ultimately determining the allocation of resources within an economy. This … Read more
The Invisible Hand: Understanding the Law of Demand and Supply The concept of supply and demand is a fundamental principle in economics, shaping the prices of goods and services in a free market. It’s the invisible hand that guides the allocation of resources, determining what gets produced, how much, and at what price. This article … Read more
