An example of a reaction where ∆G = 0 is all acid-base reactions H2O(g)→H2O(l) @STP any reaction that is over H2O(g)→ H2O(s) @STP Which reaction below is spontaneous at SATP? ∆Hº=34.1 kJ and ∆Sº=46.2 J/K ∆Hº=71.7 kJ and ∆Sº=-4.25 J/K ∆Hº=-11.1 kJ and ∆Sº=-61.8 J/K ∆Hº=9.95 kJ and ∆Sº=57.4 J/K
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) -->...
