Question 1

In the gas phase, methyl isocyanate (CH3NC) isomerizes to acetonitrile (CH3CN),
         H3C–N≡C (g) H3C–C≡N (g)
with ΔH° = –89.5 kJ/mol and ΔG° = – 73.8 kJ/mol at 25°C.  Find the equilibrium constant for this reaction at 100°C.
◦ 1.68 × 10–10

◦ 5.96 × 109

◦ 2.16 × 1010

◦ 4.63 × 10–11

◦ 8.64 × 1012


Question 2

Kw for the auto-ionization of water, H2O(l) → H+(aq) + OH– (aq), is 1.0 × 10–14.  What are the signs (+/–) of ΔS° and ΔH° for the reaction at 25°C?
◦ ΔS° = (+) and ΔH° = (+)
◦ ΔS° = (+) and ΔH° = (–)
◦ ΔS° = (–) and ΔH° = (+)
◦ ΔS° = (–) and ΔH° = (–)
