It is given that, sulfur undergoes a phase change from the rhombic crystal structure to the monoclinic crystal form at temperatures above 95 ° C . The sign of Δ S and Δ H is to be predicted for this change. The form of sulfur that has the more ordered crystalline structure is to be identified. Concept introduction: Entropy is the measure of degree of disorder or randomness. The value of Δ S is calculated using the formula, Δ S = Δ H T .
