kinetic molecular theory for gases

The molecules in a solid are very closely packed. The inter-molecular force of attraction is very strong in solids. Hence solids have a definite size and shape. Molecules of a solid vibrate about their mean position. Molecular structure of a solid Solids cannot be compresse..

From kinetic theory, Since the rate of diffusion of a gas is determined by the molecular speed,..

> are their densities, then Molecular mass is twice the vapour density, substituting this in the above equation, we have where M 1 and M 2 are the molecular masses of the two gases. Thus, the rate of diffusion of gases are inversely proportional to the square..

. Transition State explains the rate of reaction in term of formation of a transition state of reacting molecules. The formation of transition state requires energy of activation. Transition state theory connects kinetic rates with thermodynamic properties of reactants and the t..

Physical state and smell Haloalkanes are colorless, sweet-smelling liquids. The lower members like methyl chloride, methyl bromide and ethyl chloride are colorless gases while members having very high molecular masses are solid..

Calculate gram molecular weights of the following gases:a. N 2 (if 360 cm 3 at STP weighs 0.45g)b. Cl 2 (if 308 cm 3 at STP weighs 0.9..

The theory put forth by Darwin and Wallace gained wide acceptance. However, in the light of modern evidences, it was slightly modified and called the neo-Darwinism. In neo-Darwinism, organic evolution is by natural selection of inherited characters. It utilises evidences from various fiel..

when T = 0, then C = 0 This leads us to the following definition of 'absolute zero of temperature'. Absolute zero of temperature may be defined as that temperature at which the rms velocities of the gas molecules become zero. In other words, all molecular motion ceases at absolute zero ..

Introduction - Today the fact that all matter is made up of atoms is universally accepted. Realisation of the atomic constituents of matter began in 1828 when Scottish botanist Robert Brown observed a random ceaseless motion of pollen grains suspended in a liquid. Many macroscopic properties and ph..

Avogadro's Hypothesis - In trying to correlate Dalton's atomic theory with Gay Lussac's law of gaseous volume, Berzelius put forward the hypothesis that equal volumes of all gases contain equal number of atoms under similar conditions of temperature. However, it was found that e..
