જો \(\mathrm{Br}_{2(l)}\) ની પરમાણ્વીયકરણ એન્થાલ્પી  \(\mathrm{x}\; \mathrm{kJ} / \mathrm{mol}\) અને \(\mathrm{Br}_{2}\) માટે બંધ એન્થાલ્પી \(y \;\mathrm{kJ} / \mathrm{mol}\) હોય તો તેઓ વચ્ચેનો સંબંધ જણાવો.

  1. A is \(x = y\)
  2. B is \(x < y\)
  3. C કોઈ સંબંધ નહીં
  4. D is \(x > y\)
Verified Solution

Answer & Solution

Correct Answer

(D) is \(x > y\)

Step-by-step Solution

Detailed explanation

Enthalpy of atomisation of \(\mathrm{Br}_{2}(l)\) \(\mathrm{Br}_{2}(l) \stackrel{\Delta \mathrm{H}_{\mathrm{vap}}}{\longrightarrow} \mathrm{Br}_{2}(\mathrm{g}) \stackrel{\Delta \mathrm{H}_{\mathrm{BE}}}{\longrightarrow} 2 \mathrm{Br}(\underline{\mathrm{g}})\)…
