Example thermodynamic diffuser problem

WebIn Chapter 6, we define a diffuser as a flow geometry that converts kinetic energy into pressure, or ∂ Vs < 0 and ∂ ps > 0 in the direction of flow. Consequently, a converging … 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.
