The heat of vaporization δhv of acetic acid hch3co2 is 41.0 /kjmol. calculate the change in entropy δs when 954.g of acetic acid condenses at 118.1°c. be sure your answer contains a unit symbol. round your answer to 3 significant digits.

The change in entropy is -1.66 kJ/K.

Explanation:

Heat of vaporization of acetic acid = 41.0 kJ/mol

Heat of condensation of acetic acid = -41.0 kJ/mol

Mass of acetic acid = 954 g

Condensing temperature of acetic acid =118.1 °C = 391.25 K

Moles of acetic acid =

Heat evolved during condensation of 15.8867 moles of acetic acid:

Entropy change = ΔS =

The change in entropy is -1.66 kJ/K.
