Behaviour of Real Gases: Deviation from Ideal Gas Behaviour

If 1 gram of each of the following gases are taken at STP, which of the gases will occupy (a) greatest volume and (b) smallest volume?

\[\ce{CO, H2O, CH4 , NO}\]

Maximum deviation from ideal gas is expected from

In what way real gases differ from ideal gases.

Explain whether a gas approaches ideal behavior or deviates from ideal behaviour if more gas is introduced into the same volume and at the same temperature.

Match the following graphs of ideal gas with their co-ordinates:

Graphical representation	x and y co-ordinates
(i)	(a) pV vs. V
(ii)	(b) p vs. V
(iii)	(c) p vs. `1/V`

Which of the following gases would you expect to deviate from ideal behavior under conditions of low-temperature F₂, Cl_2, or Br₂? Explain.

Calculate the volume occupied by 8.8 g of CO₂ at 31.1°C and 1 bar pressure. R = 0.083 bar L K^–1 mol^–1.

Choose the correct option for the total pressure (in atm.) in a mixture of 4g \[\ce{O2}\] and 2g \[\ce{H2}\] confined in a total volume of one litre at 0°C is ______.

[Given R = 0.082 L atm mol⁻¹K⁻¹, T = 273 K]
