JEE Mains · Chemistry · STD 11 - 5. Thermodynamics and thermochemistry
For which of the following processes, \(\Delta S\) is negative?
- A \(C\) (diamond) \(\to\) \(C\) (graphite)
- B \(N_2(g,\,1\,atm) \to N_2(g,\,5\,atm)\)
- C \(N_2(g,\,273\,K) \to N_2(g,\,300\,K)\)
- D \(H_2(g) \to 2H(g)\)
Answer & Solution
Correct Answer
(B) \(N_2(g,\,1\,atm) \to N_2(g,\,5\,atm)\)
Step-by-step Solution
Detailed explanation
\((a)\) When diamond is converted into graphite when it is heated to \(1500\,^oC\) and entropy is increased so \(\Delta S > 0\) \((b)\) When pressure increases then molecules of gas will come closer and intermolecular distance decreases so entropy will also decrease and…
