(a) Under what condition will the enthalpy change of a process equal the amount of heat transferred into or out of the system?
(b) During a constant-pressure process, the system releases heat to the surroundings. Does the enthalpy of the system increase or decrease during the process?
(c) In a constant pressure process, ?H = 0.What can you conclude about ?E, q, and w?
Metals ions can also be placed in a spectrochemical series. In this case, larger effective nuclear charges generally lead to larger values for (delta) . Based on this principle, predict a spectrochemical series for the following ions
