MTNAT2 marksNeeds review
Pure orthorhombic sulfur transforms to stable monoclinic sulfur above 368.5 K. Applying Third law of thermodynamics, the value of entropy (in J K
) of transformation at 368.5 K is __________ (answer up to two decimal places)Given:
i. Entropy change associated with heating orthorhombic sulfur from 0 K to 368.5 K is 36.86 J K
.
ii. Entropy change associated with cooling monoclinic sulfur from 368.5 K to 0 K is −37.8 J K
