importance of first order kinetic energy equations

. The sum of all the orders measured for a reaction gives the overall order of the reaction. Rate constant is the rate of a reaction when the concentration of all the reactants is unity. Rate constant of a reaction is determined from the rate law or its integrated form. Rate of ..

> How do infrared and g - rays differ in their (i) wavelength and (ii) penetrating power. Suggested Answer:- (i) g - rays have much shorter wavelengths of the order of 10 - 1 3 m while the infrared have longer wavelengths of the order of 10 - 6 or more. (ii) g - rays h..

Internal Energy - Internal energy is one of the most important concepts in thermodynamics. Energy changes in a body sliding with friction. Warming a body increases its internal energy and cooling the body decreases its internal energy. How..

Potential energy is the energy possessed by an object by virtue of its position or condition. Kinetic energy = 1/2 mv 2 Potential energy = mgh Law of conservation of energy states that energy can neither be created nor ..

Example 7: Hydrogen (H 2 ) gas reacts with bromine (Br 2 ) gas to give hydrogen bromide vapor. The chemical reaction is represented by the equation as follow..

First Law of Thermodynamics or Law of Conservation of Energy - The total energy in the universe is present either as kinetic energy or as potential energy. For example, the water stored in a dam possesses potential energy by virtue of its ..

>Simple reactions are those, which involve a single elementary reaction. The rate law can be written from the stoichiometry of the chemical equation. One such reaction is the gas phase reaction of ozone (O 3 ) with nitric oxide (NO). This bimolecular reaction exhibits second order..

Radioactivity Spontaneous emission of active rays by certain unstable elements. Three types of radiations are: (i) Alpha particles He 2 + ion (Helium nuclei). (ii) Beta - rays - consist of electrons. (iii) Gamma - rays - High energy electromagnetic rays. Emission of alpha part..

In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reactio..

The Liquid State - The liquid state lies between the gaseous and the solid state. Liquids are neither completely disordered nor completely ordered. The cohesive forces between the liquid particles are strong enough to keep them together but these particles do not occupy fixed lattice site..
