2SO(2) + O(2) -> 2SO(3) 12. If 0.60 moles of SO2 are present, how many moles of O2 are required to
complete the reaction?
13. How many grams of SO3 could be produced if 384.4 g of SO2 are burned
completely?
14. What is the theoretical yield of SO3 when 50 molecules of SO2 and 30
molecules of O2 are allowed to react?

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.
