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?
Frequently Asked Questions
What scientific concept do you need to know in order to solve this problem?
Our tutors have indicated that to solve this problem you will need to apply the Spontaneous Reaction concept. You can view video lessons to learn Spontaneous Reaction. Or if you need more Spontaneous Reaction practice, you can also practice Spontaneous Reaction practice problems.
What professor is this problem relevant for?
Based on our data, we think this problem is relevant for Professor Dodson's class at UNR.
