Explain the deviation of the following gases from ideal behaviour on the basis of the pV vs. p plot . CO, `CH_4`, `H_2` and He.

Why do real gases deviate from ideal behaviour?

Give reasons for the deviation of real gases from the ideal gas behaviour.

Le Chateller's principle helps to explain the effect of change in confitions on equilibrium. Discuss the effect of pressure in the following equilibrium on the basis of le Chateller's principle: CO_(g) + 3H_(2(g)) harr CH_(4(g)) + H_2O_(g)
