For a gas deviation from ideal behaviour is maximum at :

Mention three characteristics of ideal solutions . What cause deviation from ideal behaviour ? Discuss the + ve deviation from ideal behaviour for ilquid pairs

Assertion: Helium shows only positive deviations from ideal behaviour. Reason: Helium is an inert gas.

Is the vapour pressure for the solution showing Positive deviation from ideal behaviour is more or less ?

Vapour pessure of a liquid or a solution is the pressure exerted by the vapour in equilibrium with the liquid or solution at a particular temperature. It depends upon the nature of the liquid and temperature. It depends upon the nature of the liquid and temperature. According to Raoult's law in a solution, the vapour pressure of a component at a given temperature is equal to the mole fraction of that component in solution multiplied by the vapour pressure of that component in hte pue state. this solution in which each component obeys Raoult's law are called ideal solutions. there are two types of non ideal solutions, showing positive deviations and negative deviations from ideal behaviour. If liquid A and B form ideal solution, then

Write difference between positive and negative deviation from Ideal behavior ?

A gas will approach ideal behaviour at

Which solution shows +ve(positive) deviation from the ideal behaviour ?

For a certain gas which deviates a little from ideal behaviour, a plot between P/p vs P was found to be non- linear . The intercept on y-axis will be :

Under which of the following sets of conditions is a real gas expected to deviate from ideal behaviour? (I) High pressure, small volume (II) High temperature , low pressure (III) Low temperature, high pressure
