Question 1

What are the signs are expected for the entropy change ΔS and free energy change ΔG for the reaction below?

N2H4(l) + N2O4(l) → 3 N2(g) + 4 H2O(g)ΔH = -1049 kJ

◦ ΔS = + and ΔG = -
◦ ΔS = + and ΔG = +
◦ ΔS = - and ΔG = +
◦ ΔS = - and ΔG = -

Question 2

A 0.010 M solution of which of the following would have the lowest pH?
◦ NH2OH (Kb = 9.1 × 10-9)
◦ N2H4 (Kb = 8.0 × 10-7)
◦ CH3NH2 (Kb = 3.7 × 10-4)
◦ NH3 (Kb = 1.8 × 10-5)
