Notes On Gaseous State (BSc and Integrated Standard For all Concerned Entrance Examination)

 Notes On Gaseous State      This page provides you all details about the gaseous state of BSc standard. Concerned problems will be solved at the end of each concept. Continue till the end to find the easiest explanation of every concept you need in this regard . Postulates of Kinetic Theory of Gases: 1. All gas consist of a very large number of minute particles, called molecules.  2. The gas molecules are extremely small in size and are separated by large distance. The actual volume of the gas molecules is thus negligible as compared to the total volume occupied by the gas.  3. The pressure exerted by the gas is due to the bombardment of the molecules on the walls of the vessel.  4. The gas molecules collide with one another and also with the walls of the vessels. These collisions are perfectly elastic and there is no loss of energy during these collisions.  5. The distance between the gas molecules are very large. Thus, there is no effective force of attraction or r

CHSE_CBSE_ 2_3_ Marks Chemistry Questions and Answers (TOPIC: Solution)

  2 or 3 marks CHSE/CBSE Chemistry Questions and Solutions  (Topic: Solution)   1. State and explain  Henry's law. Ans:   The dependence of solubility of a gas in a solvent on pressure can be quantitatively expressed by Henry’s Law. This law can be expressed in a number of ways: (a)   T he solubility of a gas (in mol ltr -1 ) in a liquid at a particular temperature is directly proportional the partial pressure of the gas in equilibrium with the liquid at that temperature.       Mathematically, s α p   => s = k p,  where   s= solubility, Unit of  k = mol L -1  atm -1 (b)   The  amount of a gas dissolved (expressed in terms of mole fraction) in a definite volume of solvent at constant temperature is directly proportional to the partial pressure of the gas present in equilibrium with the solvent at that temperature.      Mathematically,  p g  = k H   X g     Where, KH is the Henry law constant. A gas having high solubity comparision to other has lower KH value. 2. What is relative
