The equations below show how to set up the calculations. 0.854 mol Ag × 1 mol Cu 2 mol Ag 0.854 mol Ag × 1 mol AgNO3 1 mol Ag Did you set up the calculations correctly? Yes, and I got the correct answer. Yes, but I got the wrong answer because I made a mathematical error. No, I did not set up the equation correctly.

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.
