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
The intensive property among these quantities is
(1) Enthalpy
(2) Mass/volume
(3) Mass
(4) Volume
Among mass, volume, density and specific volume of a gas, the intensive properties are:
1. Density and specific volume
2. Volume and density
3. Specific volume and mass
4. Density only
| Assertion (A): | The standard heat of combustion of a hydrocarbon compound is an intensive property. |
| Reason (R): |
The standard heat of combustion is considered an intensive property because the amount of the substance is defined as 1 mole. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
