Question

The enthalpy change for the conversion of 1 Cl2 (g) to Cl– (aq) is (–)__________ KJ mol–1 (Nearest Integer) Given : , mol kJ H , mol kJ H – Cl eg – ) g ( Cl dis ) g ( Cl hyd mol kJ H ) g ( NTA (610) RESO. (610)

Prashant Kotian · Accepted Answer

1 Cl2(g) Cl–(aq) Cl(g) Cl–(g) Hhyd. of Cl–(g) 1 B.E. Heg of Cl(g) r H  = 1 × B.E. + Heg + Hhyd. r H  = 1 × 240 + (–350) + (–380) = –610 kJ/mole
