Question 1
1
The molar heat of fusion (AfusH) for acetone is 5.7 kJ/mol and the molar heat of vaporization
(AvapH) for acetone is 31.3 kJ/mol. At 1.0 bar pressure, acetone melts at -95 °C and boils at
56°C.
1.1 Calculate the entropy change for boiling 1 mole of acetone at 56°C.
Transcribed Image Text:Question 1 1 The molar heat of fusion (AfusH) for acetone is 5.7 kJ/mol and the molar heat of vaporization (AvapH) for acetone is 31.3 kJ/mol. At 1.0 bar pressure, acetone melts at -95 °C and boils at 56°C. 1.1 Calculate the entropy change for boiling 1 mole of acetone at 56°C.
Expert Solution
Step 1

Entropy change for boiling depends on molar enthalpy of vaporization and not on molar heat of fusion.
