question 71

Multiple Choice

A 0.42-kg quantity of ethanol, in the liquid state at its melting point of $- 114.4 ^ { \circ } \mathrm { C }$ , is frozen at atmospheric pressure. The heat of fusion of ethanol is $1.04 \times 10 ^ { 5 } \mathrm {~J} / \mathrm { kg }$ , and its molecular mass is $46.1 \mathrm {~g} / \mathrm { mol }$ . What is the change in the entropy of the ethanol as it freezes?

• A) \(280 \mathrm {~J} / \mathrm { K }\)
• B) \(250 \mathrm {~J} / \mathrm { K }\)
• C) \(- 280 \mathrm {~J} / \mathrm { K }\)
• D) \(- 250 \mathrm {~J} / \mathrm { K }\)
• E) \(- 310 \mathrm {~J} / \mathrm { K }\)
