F. additional problems solve the following problems in the space provided. show your work. 30. the gaseous product of a reaction is collected in a 25.0-l container at 27°c. the pressure in the container is 216 kpa, and the gas has a mass of 96.0 g. what is the molar mass of the gas? 31. the separation of uranium-235 from uranium -238 has been carried out using gaseous diffusion. calculate the relative rates of diffusion of gaseous uf6 containing these isotopes. molar mass of uf6 containing uranium-235 = 349.0 amu. molar mass of uf6 containing uranium-238 = 352.0 amu.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
