The double bond character added to the c–n bond by resonance results in restricted rotation about the c–n bond, explaining why the atoms about the peptide bond all lie in a plane. in the structure at the right, select all of the atoms and bonds that lie in the peptide plane by clicking on them. (when selected, and atom or bond will turn green. if one is selected by mistake, click on it again to deselect.)

step-by-step explanation:

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.
