To an equilibrium mixture of Some helium, an inert gas, is added at constant volume. The additiona of helium causes the total pressure to double. Which of the following is true?
1 The concentration of all three gases is unchanged.
2 The concentration of sulphur trioxide increases.
3 The numberof moles of sulphur trioxide increases.
4 The concentration of sulphur dioxide increases.
Explanation:
As volume remains constant, the concentration of the three gases will remain unchanged on adding the helium. Since, the inert gas is added at constant volume, i.e. the volume is not allowed to increase, the concentrations of all the free gases remain unchanged.

For the equilibrium, , Increase in temperature
1 favours the formation of
2 favours the decomposition of
3 does not affect equilibrium of
4 stop the reaction
Explanation:
The given reaction is exothermic and according to Le-Chatelier principle high temperature shifts the equilibrium in backward direction. In other words, high temperature favours the decomposition of .

According to Le-equilibrium's Principle, the addition of temperature to the following reaction: (g) will cause it to the right. This reaction is therefore,
1 Exothermic
2 Unimolecular
3 Endothermic
4 Spontaneous
Explanation:
For the endothermic reaction with increase in temperature rate of forward reaction increases. According to Le-equilibrium's principle when the concentration of a chemical will be shift the equilibrium to the side that would counter the change in concentrating. In this reaction temperature is increased then the process is endothermic.

The basic principle of Cottnell' precipitation is
1 Le-Chatelier's principle
2 Peptisation
3 Neutralization of charge on colloidal particles
4 Scattering of light
Explanation:
In Cottnell's precipitator, the charged particles are attracted towards the walls of precipitator, here they lose their charge and coagulate. Hence, the basic principle of Cottnell's precipitator is the neutralisation of charge on colloidal particles.
