Calculate the molar entropy change when a sample of water is heated from 110 to 120 ºC at constant pressure given the molar heat capacity of H2O (g) at constant pressure = 33.58 J mol-1 K-1. Can cooling from 200 ºC to 110 ºC bring an increase in the entropy of the system?
The entropy change due to the expansion of a perfect gas is given by: . Sketch the dependence of on the volume ratio between and hen calculate the final volume following the expansion of 1 mole of gas from an initial volume of 24 dm3 given .
The molar entropy of 1,3-dioxane (C4H8O2) is 196.6 . What is the change in the molar Gibbs energy when it is heated from 298 K to 323 K? Assume the molar entropy independent of T.
