Chemical Bond

For a detailed analysis of a chemical system, it is necessary to know all the relevant intermediates and initial reactions of the potential energy surface…

Exothermic reaction: Exothermic reaction is the reaction where heat energy evolves. C (graphite) + O2 → CO2; ∆H298K = – 393.4 Kj mol-1 Endothermic reaction:…

Hess’s law is known as after Russian Chemist Germain Hess. Hess helped formulate the early standards of thermochemistry. His famous paper, which was published in 1840, included his law. Hess’s law: If the initial and…

Ionic product of water: The dissociation of water, H2 O+ ↔ H+ + OH– According to law of mass action, K = [H+] x [OH–]…

The conjugated base of strong acid is weak and the conjugated base of weak acid is strong. It can be explain—clearly by reversible reaction. HB…

The principle of Le Chateliar: When a system is at equilibrium, a change in any one of the factors (such as temperature, pressure, concentration) upon…

The constant KC is called the equilibrium constant and applies to reactions in solution. It contains only concentration terms. It should not included terms for…

Chemical equilibrium: A chemical equilibrium in a system is the state of the system when there is no observable change in the concentration of the…

Dynamic equilibrium: When a reversible reaction reaches at equilibrium, then it seems to be stopped. Because, in this situation there seems to no change in…

In a particular temperature and time the rate of any reaction is proportional to the activation mass (Molar concentration and partial pressure) of the reactants…
