The enthalpy of fusion of water is 1.435 kcal / mol . The molar entropy change for the melting of ice at 0^ C is

Options

  1. A10.52 cal /( mol K )
  2. B21.04 cal /( mol K )
  3. C5.260 cal /( mol K )
  4. D0.526 cal /( mol K )

Correct answer

C. 5.260 cal /( mol K )

Step-by-step solution

Molar entropy change for the melting of ice, aligned S_ melt & = H_ fusion T & = 1.435 kcal / mol (0+273) K & =5.26 10⁻³ kcal / mol K & =5.26 cal / mol K aligned
