Critical temperature of NH(3) and SO(2) ...

Critical temperature of `NH_(3)` and `SO_(2)` are 405.0 and 430.3 K respectively. Which one will have higher value of van der Waals constant 'a' and why ?

Text Solution

AI Generated Solution

To determine which substance, NH₃ (ammonia) or SO₂ (sulfur dioxide), has a higher value of the van der Waals constant 'a', we need to analyze the relationship between critical temperature and intermolecular forces. ### Step-by-Step Solution: 1. **Understanding Critical Temperature**: - The critical temperature (Tc) is the temperature above which a gas cannot be liquefied, regardless of the pressure applied. It reflects the strength of intermolecular forces in a substance. 2. **Given Data**: ...
