🤓 Based on our data, we think this question is relevant for Professor Kuntz's class at UNC.
We’re being asked to determine if the given process is spontaneous.
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
As shown here, one type of computer keyboard cleaner contains liquefied 1,1-difluoroethane (C2H4F2), which is a gas at atmospheric pressure. When the nozzle is squeezed, the 1,1-difluoroethane vaporizes out of the nozzle at high pressure, blowing dust out of objects.
Based on your experience, is the vaporization a spontaneous process at room temperature?
