Which of the following conditions represents an equilibrium?
1 Freezing of ice in an open vessel; temperature of ice is constant.
2 Few drops of water is present along with air in a balloon; temperature of balloon is constant
3 Water is boiling in an open vessel over stove; temperature of water is constant.
4 All the statements are correct for the equilibrium.
Explanation:
Equilibrium can be achieved only in a closed vessel.

In the reaction, . Which of the graph is/are correct?
1 I and II
2 I, II and III
3 II and III
4 I and III
Explanation:
As time passes conc. of reactants decreases and products increases. At equilibrium, conc. of reactants & products do not change with time.

Assertion : Reaction between iron and steam is irreversible if carried out in the open tube. Reason : An irreversible reaction cannot take place in the reverse direction.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Iron reacts with steam to form iron oxide as follows: In an open tube, continuous exposure to oxygen from the air drives the iron oxidation reaction towards iron oxide formation. But in a controlled environment (isolating iron from the air) the reaction becomes potentially reversible by preventing continuous oxidation. So option (2) is correct.

Which of the following is a characteristic property of equilibrium?
1 Number of moles of reactants and products is always equal
2 Catalyst affects the equilibrium state
3 It never proceeds to completion
4 Rate of forward and backward reactions are not equal
Explanation:
(1)Number of moles of reactants and products is always not same (2) Catalyst fastens the existence of equilibrium but does not affect the equilibrium state. (4) At equilibrium, rate of forward reaction is equal to the rate of backward reaction. So option 3 is correct
