What is the ratio of ground-state nickel atoms (in which e is defined as zero) to nickel atoms that are in the first excited state of 201 cm21 at 298 k? (the spectrum of ni atoms is complicated by the existence of such an excited state. does your answer explain why? ) assume the two states have the same degeneracies.

fun caring loving person

girl imma just put my comment here because i need a couple point okurrttt

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.
