kinetic molecular theory of gases molecules of an ideal gas

Gram molecular weight (GMW) or mole is the relative molecular mass of a substance expressed in grams. It is also called gram molecular weight of that element. Gram molecular volume (GMV) or molar volume is the volume occupied by one-gram molecular w..

Let us consider one-gram molecule (mole) of the gas. Let M and V be its mass and volume respectivel..

It is clear from equation (2) that the mean kinetic energy of a molecule is directly proportional to the Kelvin (or absolute) temperature of a gas. When the temperature of the gas is increased, the mean kinetic energy of the molecules ..

. Transition state is supposed to be in equilibrium with the reactants. It also has a very short life. That is why, when it was proposed in the 1930s, it was not possible to study the transition state with the techniques available then. With the help of laser pulses of femtosecond to picoseconds le..

Gases do not posses any definite shape or volume. They will completely fill all the space available to them. The tendency of a gas to fill the available volume within a container is the result of the freedom that gas particles have to move everywhere in the avail..

Equilibrium Between a Gas and its Solution - Gases can be dissolved in suitable liquids. The solubility of a gas in any liquid depends upon: Nature of the gas and the liquid. Temperature of the liquid. Pressure of the gas over the surface of the sol..

Relative Molecular Mass - Relative molecular mass or RMM is the molecular weight of an element or an compound. It is the number of times one molecule of the substance is heavier than 1/12 the mass of an atom of carbon (C 1 2 ). Gram molecular mass i..

. As a result, a large number of energy levels are crowded together into 'bands'. Because of these energy bands, the molecular orbital theory of metals is also known as band theory. As an illustration the bonding in sodium metal can be studied. Imagine that a crystal o..
