In van der Waals equation of state of the gas law, the constant b is a measure of (a) intermolecular repulsions.

Vander Waals equation for n mole of gas is (+2/2)(−)=.

The equation of state is given by, pV = nRT ……….. (i) Where, p → Pressure of gas V → Volume of gas n→ Number of moles of gas R → Gas constant T →...

Physical significance of ‘a’: ‘a’ is a measure of the magnitude of intermolecular attractive forces within a gas. Physical significance of ‘b’: ‘b’ is a measure of the volume of...

(d) (i), (ii) and (iv)

Solution: 90°, as they add up to 180°

Salim would get the most accurate length. The reason is that in this case the length of the table can be measured in one go because the measuring tape is...

(i) Raoult’s law: It states that for any solution, the partial pressure of each volatile component in the solution is directly proportional to its mole fraction. (ii) Henry’s law: It states...

(1) Critical temperature ∝ vanderwaal constant(a) maximum "a" => gas with maximum TC => easiest liquification = NH3

Intermolecular forces tend to keep the molecules together but thermal energy of the molecules tends to keep them apart. The three states of matter are the result of the balance...

 a) At constant vol. the total pressure would increase due to inert gas addition but the conc. of the reactants and products will do not change hence no effect on...
