🤓 Based on our data, we think this question is relevant for Professor Dodson's class at UNR.
We’re being asked to determine at what temperature is the vaporization of water nonspontaneous. The standard free energy change of a reaction (ΔG) is given by the following equation:
Recall that if:
• ΔG < 0 or ΔG = (–); the reaction is spontaneous
• ΔG = 0; the reaction is at equilibrium
• ΔG > 0 or ΔG = (+); the reaction is non-spontaneous
Consider the vaporization of liquid water to steam at a pressure of 1 atm.
In what temperature range is it a nonspontaneous process?
