Answer» e of ACETONE requires less heat to vaporise than 1 mol of water. Which of the two liquids has a higher ENTHALPY of vapourisation?o Enthalpy of vapourisation is defined as the heat CONSUMED by a liquid to transform into the gaseous form at a certain pressure and temperature.o 1 mole of acetone requires less heat than 1 mole of water to VAPORIZE. So, water consumes less heat than the same amount of acetone for vapourisation.Hence, amongst the two liquids, water has a higher enthalpy of vapourisation (CONSUMING higher heat energy).Therefore, ∆Hvapourisation (water) > ∆Hvapourisation (acetone). |
