The entropy change for the fusion of 1 mol of a solid which melts at 27^ C is (latent heat of fusion =600 cal mol ⁻¹ )

Options

  1. A2 cal K ⁻¹
  2. B22.2 cal K ⁻¹
  3. C180 k cal K
  4. D0.5 cal ⁻¹ ~K

Correct answer

A. 2 cal K ⁻¹

Step-by-step solution

S_ fus = H_ fus T Given, aligned T & =27+273 & =300 ~K S_ fus & = 600 300 =2 cal deg ⁻¹ aligned
