1) Which of the following reactions is likely to have a positive ΔS?
a. Na(l) --> Na (s)
b. 2 C4H10(g) + 13 O2(g) --> 8 CO2(g) + 10 H2O(g)
c. CaCO3(s) + 2 HCl(aq) --> CaCl2(aq) + H2O(l) + CO2(g)
d. 6 CO2(g) + 6 H2O(g) --> C6H12O6(s) + 6 O2(g)
2) ATP (aq) + H2O(l) <--> ADP (aq) + phosphate(aq), ΔG° = -30.5 kJ/mol. What is the value of ΔG in at 310K assuming [ATP] = 0.25M and [ADP] = [phosphate] = 0.030M?
3) H2(g) + CO2(g) <-->H2O(g) + CO(g), Kp = 5.50. Calculate ΔG when pressures are: PH2 = 0.33 atm, PCO2 = 0.45 atm, PH2O = 0.95 atm, PCO = 1.90 atm at T = 298K.
4) When ΔG is positive, ΔG° is?
a. Positive
b. Negative
c. Equal
d. None of the above
