Question

Calculate the entropy change when 1 mole of ethanol is evapoureted at 351K . The molar heat of vapourasation of ethanol is 39.84 kJ mol-1

Answer 1

260 million kilometre per hour is Amsterdam all of the vibration is known as operation

Answer 2

Answer:

We know that

ΔSvapour = ΔHvapour/Tbp

Given, ΔSvapour =109.8JK^−1 mol^−1

Tbp =78.5+273=351.5K

Substituting these values in above equation, we get

109.8= ΔHvapour/351.5

ΔHvapour=38594Jmol^−1 =38.594kJmol^−1

Hope this is helpful for you.
