6. Calculate the entropy change when 2 moles of gaseous water are formed at 100°C and 1 atm from hydrogen and oxygen gas at the same temperature. H2(g) = 130.57 J/K Standard molar entropy: H2O(g) = 188.72 J/K O2(g) = 205.04 J/K Constant volume molar heat capacity: H2O(g) = 25.3 J/ K O 2(g) = 21.1 J/K Constant pressure molar heat capacity: H2O(g) = 33.6 J/K O2(g) = 29.4 JK H2(g) = 20.5 JK H2(g) = 28.8 J/K

1 kg of benzene and 1 kg of toluene are mixed and maintained at 60°C. The vapor pressures of the pure components at 60°C of benzene and toluene are 53 and 18.5 kPa, respectively. If the pressure is to be reduced, predict the pressure at which the mixture will start to boil. Assess the fraction of the first bubble of vapor.

Oxygen and Nitrogen are mixed adiabatically at 80°C. Oxygen has an initial volume of 20 meters cubed and a pressure of 100 bar. Nitrogen has a volume of 90 meters cubed and an initial pressure of 50 bar. If the system has no change in volume, calculate: Final pressure Mass AND mole fractions in % Entropy change of EACH gas

Calculate the change in entropy when one mole of metallic aluminum is heated at one bar pressure from an initial temperature of 25 °C to a final temperature of 750 °C. The molar heat capacities of solid and liquid aluminum at one bar pressure are 29.2 J mol K1 and 31.75 J mol K, respectively. The specific enthalpy of fusion of aluminum at its melting point (660.46 °C) is 396.57 J g1. The molar mass of aluminum is...

Two thoroughly insulated rigid tanks are joined by a valve. One of them contains N2 (2 kg, 27 °C, 500 kPa, molar mass = 28.013 g/mol, Cv = 0.743 kJ/kg.K) while the other contains O2 (6 kg, 40 °C, 225 kPa, molar mass = - 31.999 g/mol, Cv = 0.658 kJ/kg.K). If the connecting valve is fully opened, determine the equilibrium mixture temperature and pressure. Use RN2 = 0.2968 kJ/kg.K and Ro2 = 0.2598 kJ/kg.K.
