QJEEM18Chcaa6: JEE Main 2018 Chemistry - Class 11 JEEM18Chcaa6 Solution: For which of the following processes, Δ S is negative ?

For which of the following processes, ΔS is negative ?

Multiple Choice Options

  • A H2(g) → 2H(g)
  • B N2(g, 1 atm) → N2(g, 5 atm)
  • C C(diamond) → C(graphite)
  • D N2(g, 273 K) → N2(g, 300 K)

Step-by-Step Verified Solution

N2(g, 1 atom) ⟶ N2(g, 5 atom)

Here pressure increases. When pressure increases then the molecules of will come closer and intermoleculer distance decreases, so entropy will also decreases and ΔS<0.
