Warming ammonium chloride with sodium hydroxide in a test tube is an example of:

1. closed system

2. Isolated system

3. open system

4. None of these

Which of the following are not state functions?

(I) q + W                        (II) q

(III) W                           (IV) H-TS

1. (I) and (IV)                     

2. (II), (III) and (IV)

3. (I) , (II) and (III)               

4.  (II) and (III)

Point out the wrong statement in relation to enthalpy

1. It is a state function

2. It is an intensive property

3. It is independent of the path followed for the change

4. Its value depends upon the amount of substance in the system

Mark the correct statement 

1. For a chemical reaction to be feasible, ΔG should be zero

2. Entropy is a measure of order in a system

3. For a chemical reaction to be feasible, ΔG should be positive

4. The total energy of an isolated system is constant

Internal energy is an example of [Pb. PMT 2000]

(1) Path function

(2) State function

(3) Both (1) and (2)

(4) None of these
