CHAPTER 17 HOMEWORK 1. The thermodynamic parameter which relates to the even dispersal of energy throughout a system is called_entropy 2. A system which has many microstates will have (higher, lower) entropy than (higher, lower) entropy than undissolved NaCl. 4. Unlike enthalpy, absolute entropy can be measured. This is because the entropy of a perfect crystalline solid at 0 K is considered to be 5. The statement described in Question 4 is often referred to as the Thermodynamics. a system which less microstates. 3. NaCl dissolved in water has Law of 6. For a spontaneous process, the entropy of the universe is always greater than 0. This statement is often referred to as the Law of Thermodynamics. 7. The entropy for the reaction N2(g) + 3H2(g) = 2NH3(g) would be expected to be (positive, negative) 8. You chose your answer for Question 7 because the reaction produces less than it consumes 9. For a process to be spontaneous, which thermodynamic parameter must be less than zero? 10. Energy in living systems is usually stored in which molecule? 11. The entropy of vaporization of benzene is 87.8 J/K.mol. If benzene boils at 80.1°C, calculate the entropy change for complete vaporization of 200 grams of benzene at 80.1°C. The molar mass of benzene is 78 grams per mole.
