1. Determine the ∆Sº using Appendix G for the following reaction. C2H5OH(l) + 3 O2(g) --> 2 CO2(g) + 3 H2O(l) Report your answer to three sig figs. Omit unit labels. Only add a - number is the sign is negative. Adding a + to a positive answer messes up the grading. 2. Which of the following equations will have a negative ∆S? A. 3 H2(g)+ N2(g) --> 2 NH3(g) B. C6H6(l)--> C6H6(g) C. NH4OH(s)--> H2O(l)+ NH3(g) D. NaCl(s) -->...
