question 68

Multiple Choice

The normal melting point of sulfur is 113 ^$\circ$ C. If a sample of solid sulfur is at 95 ^$\circ$ C, predict the signs of $\Delta$ H, $\Delta$ S, and $\Delta$ G for the melting process at this temperature.

• A) (\(\Delta\)H) > 0, \(\Delta\)S > 0, \(\Delta\)G < 0
• B) (\(\Delta\)H) > 0, \(\Delta\)S > 0, \(\Delta\)G > 0
• C) (\(\Delta\)H) > 0, \(\Delta\)S < 0, \(\Delta\)G < 0
• D) (\(\Delta\)H) < 0, \(\Delta\)S > 0, \(\Delta\)G > 0
• E) (\(\Delta\)H) < 0, \(\Delta\)S < 0, \(\Delta\)G > 0
