WebGiven that the free energy of formation of liquid water is -237 kJ / mol, calculate the potential for the formation of hydrogen and oxygen from water. To solve this problem we must first calculate ΔG for the reaction, which is -2 ( -237 kJ / mol) = 474 kJ / mol. Knowing that ΔG = -nFE o and n = 4, we calculate the potential is -1.23 V. WebThere is one problem involving an isothermal (as opposed to adiabatic) air compressor. The idea here is to cool the air (i.e., remove heat) as it is compressed. When the process is assumed to be reversible and isothermal, the heat transfer in the process can be predicted from application of the second law.
