Question
Answer the following questions based on the phase diagram (not to scale!) for sulfur dioxide , SO, , and on the following data: AHfusion = 115 J/g, AH,vap = 389 J/g, specific heat gas = 0.623 J/g-K 78 1.00 P atm 0.0017- 197.6 200.4 263.1 430.7 T Kelvin (a) What is the normal melting point? K The normal boiling point? (b) At what temperature and pressure do the three phases coexist in equilibrium? T = K, P = atm (c) Is sulfur dioxide a solid, a liquid or a gas at room temperature and pressure? If a gas, is it a permanent gas?| (d) Which is the more dense phase, the liquid or the solid?| (e) A 26.6 g sample of liquid sulfur dioxide is heated at a constant pressure of 1 atm from a temperature of 263.1 K to a temperature of 324.8 K. How much energy in kJ is required? |kJ
