Q. No.Which of the following statements is correct for the spontaneous adsorption of a gas?
| 1. | ∆ S is negative and therefore, ∆ H should be highly positive |
| 2. | ∆ S is negative and therefore, ∆ H should be highly negative |
| 3. | ∆ S is positive and therefore, ∆ H should be negative |
| 4. | -∆ S is positive and therefore, ∆ H should also be highly positive |

The Langmuir adsorption isotherm is deduced using the assumption:
| 1. | The adsorption takes place in multilayers |
| 2. | The adsorption sites are equivalent in their ability to adsorb the particles |
| 3. | The heat of adsorption varies with coverage |
| 4. | The adsorbed molecules interact with each other |
