Question

8.314J. 1 atm- 1.01325X10% Pa; 1 m2-101:760 torr-1 atm; R-0.0821 1. atm. K' mol K.1 mol Note that the different parts of question 1 are independent. Answering a part of a question wrong or skipping it altogether should not affect your ability to answer other parts correctly. iven the relationship dG-V dP-S dT which indicates that G-(P, T). Also knowing that G is a state functions (meaning the reciprocity rule applies on it), derive the relation: os OP av Using the given equation in (a) show that the following equation applies when the system is at equilibrium: dP/dT Show that the units of the left and right sides of the equation in (b) are consistent At constant pressure of 1.0 atm, one mole of steam at 100. °C is condensed reversibly to liquid water at the same T. The heat of vaporízation of water is 40.7 KJ/mol. Assuming that the steam is an ideal gas calculate W, Q, AUm ΔΗ", Δ,n, and ΔGm for the condensation process (express all the thermodynamic terms in KJ.mof, or in KJ. K'ı mol., for Δ..). Assume that the density of water at 100. C is 1.0 gr/mL. Recall that the molar mass of water is 18 gr.mol. b) AS/AV c) d)
