PROBLEM 2 (Early submission bonus of +10% if submitted by 22/2/2022, 11:59pm) This question is meant to give you practice in handling units in thermodynamics. For this problem there is no need to define systems, draw diagrams or list assumptions. However, try to practice good symbol usage habits. The Antoine Equation (which we will learn later) relates the vapor pressure of a pure substance, psat, to the temperature, T: B In(psat /kPa) = A T/K-C = where A, B, and C are substance-specific dimensionless constants. Note that the notation psat /kPa indicates that psat must be in the pressure unit of kilopascal, and likewise, T must be in Kelvin. Table B.2 in Appendix B of the SVNA textbook lists these constants for many substances. However, in older books, the constants are sometimes given for a different form of the Antoine Equation: log10(psat /Torr) = a b t/C + c where t is the temperature in degree Celsius. Suppose you are given an old table of Antoine constants a, b and c, and you want to translate it into the "modern form used in your textbook. Derive expressions of A, B and C in terms of a, b and c
