Question

The molar enthalpy of fusion of water is 6.01 kJ mol-1. The entropy change of 1 mol of water at its melting point will be (A) 22 J mol-1 K-1 (B) 109 J mol-1 K-1 (C) 44 J mol-1 K-1 (D) 11 J mol-1 K-1

Δ S=(6.01×103/(0+273))J/mol=22J/mol

Q. The molar enthalpy of fusion of water is $6.01 k J m o l^{- 1}$ . The entropy change of $1 m o l$ of water at its melting point will be

$22 J m o l^{- 1} K^{- 1}$

$109 J m o l^{- 1} K^{- 1}$

$44 J m o l^{- 1} K^{- 1}$

$11 J m o l^{- 1} K^{- 1}$

$Δ S = \frac{6.01 \times 1 0 ^{3}}{( 0 + 273 )} J / m o l = 22 J / m o l$

Q. The molar enthalpy of fusion of water is 6.01kJmol−1. The entropy change of 1mol of water at its melting point will be
