Which one of the following statements is correct?
- A \(\mathrm{N}_2\) is a brown coloured gas
- B \(\mathrm{O}_3\) is thermodynamically stable compared to oxygen
- C Rhombic sulphur is stable at room temperature
- D \(\mathrm{Cl}_2\) is a colourless gas
Answer & Solution
Correct Answer
(C) Rhombic sulphur is stable at room temperature
Step-by-step Solution
Detailed explanation
Among the allotropes of sulphur, rhombic (yellow) sulphur is more stable than the monoclinic sulphur and is stable at room temperature. Above \(369 \mathrm{~K}\), rhombic sulphur transforms into monoclinic. \(\mathrm{N}_2\) is a colourless gas, \(\mathrm{O}_3\) is less stable…
