Question 1

Given the following data, calculate the normal boiling point for formic acid (HCOOH).
 
ΔHf°(kJ/mol)
S°(J/mol K)
HCOOH(l)
-410.
130.0
HCOOH(g)
-363
251.0
 


◦ 0.39 °C
◦ 388 °C
◦ 661 °C
◦ 279 °C
◦ 115 °C

Question 2

Given the following free energies of formation:
 
ΔGf°
C2H2(g)
209.2 kJ/mol
C2H6(g)
–32.92 kJ/mol
calculate Kp at 298 K for C2H2(g) + 2H2(g) C2H6(g)


◦ 97.7
◦ 1.10
◦ 7.95 × 1030
◦ 2.76 × 1042
◦ None of these is within a factor of 10 of the correct answer.
