The heat of vaporization of acetic acid is . Calculate the change in entropy when of acetic acid condenses at .

The question is incomplete, the complete question is;

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.

-1.67 JK-1

Explanation:

Since Heat of vaporization of acetic acid = 41.0 kJ/mol

Therefore:

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

Mass of acetic acid = 954 g

Temperature of condensation = 118.1 °C or 391.1 K

Number of moles of acetic acid = 954 g/60g/mol = 15.9 moles

Heat evolved during condensation = 15.9 moles *  -41.0 kJ/mol = -651.9 KJ

Entropy change (ΔS) = Heat evolved/ Temperature = -651.9 KJ/391.1 K

Entropy change (ΔS) = -1.67 JK-1

i believe the answer is 5,000

answer: option (b) is the correct answer.

explanation:

intensive property is the physical property which does not depend on the size of system or amount of material present in system.

for example, color, density, melting point, boiling point etc are all intensive properties.

thus, we can conclude that the boiling point and color of a substance are both examples of intensive properties because they do not depend on the amount of matter in the sample.
