The boiling points of methanol and cyclohexane are 64.7 and 80.7 °C and the heats of vaporization are 35,270 and 30,083 J mol−1, respectively. Determine the entropies of vaporization and explain the difference. 14. (a) The molecular masses of CH3NH2 and CH3F are approximately equal bu...
Moreover, in Figure 4, the error increases as the magnitude of the enthalpy of vaporization increases. In conclusion, the model is relatively satisfactory. This is because Equation (2) itself is straightforward in form and does not possess a complex mathematical form, not even using second-...
