a. Explain whether the vaporization of methanol (CH3OH) is an
exothermic or
endothermic process (motivate your answer).
b. Calculate the enthalpy change for the condensation of 2.5 g
of methanol (CH3OH) at
its normal boiling point (64.7oC) (the vaporization
enthalpy (ΔHvap) for methanol is
+37.6 kJ/mol at 64.7oC).
c. Decide whether the following reaction is exothermic or
endothermic:?
C8H16(l) + H2O(l) → C8H18O(l)
by using the following data:
1. 2C4H8(g) → C8H16(g) ∆H1o = +169
kJ
2. C8H18O(l) → 2C4H8(g) + H2O(l) ∆H2° = +394 kJ
3. C8H16(g) → C8H16(l) ∆H3 o = -39
kJ
