Explain how the heat measured in example 5.5 diffees from enthalpy change for the exothermic reactions described by the following equation:
hcl + naoh ? nacl + h2o
reference example 5.5
heat produced by an exothermic reaction
when 50.0ml of 0.10 m hcl and 50.0 ml of 0.10 m naoh, both at 22.0c are added to a cofee cup calorimeter, the temperature of the mixture reaches a maximum of 28.9 c. what is the approximate amount of heat produced by this reaction
hcl + naoh ? nacl + h2o

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.
