Equilibrium Tes...

In a reversible reaction $$H_{2} + I_{2} \leftrightharpoons 2HI$$, if the concentration of $$H_{2}$$ and $$I_{2}$$ are increased, the value of $$K_{c}$$:

 Solubility of a substance which dissolves with a decrease in volume and absorption of heat will be favoured by:

For an exothermic reaction, the equilibrium constant :

At constant pressure, the presence of inert gases:

An increase in pressure would favor the following reaction: 

The degree of dissociation of an electrolyte depends on:

Assertion A: A catalyst has no effect on the state of equilibrium
Reason R:  A catalyst influences the rates of both forward and backward reactions to the same extent.

Cottrell precipitator acts on which of the following principle?

 In the equilibrium reaction, $$N_{2} + 3H_{2} \Leftrightarrow  2NH_{3}$$, the sign of $$\Delta H$$ accompanying the reaction is;

Which of the following is not affected by change in pressure?
