Question 1

Predict the normal boiling point of triethylborane (C6H15B) using the following data:
         
 
ΔH°f (25°C)
ΔG°f (25°C)
C6H15B(l)
–194.6 kJ/mol
 9.4 kJ/mol
C6H15B(g)
–157.7 kJ/mol
16.1 kJ/mol
 

◦ 92°C
◦ –21°C
◦ 21°C
◦ 365°C
◦ 256°C

Question 2

Sodium carbonate can be made by heating sodium bicarbonate:
         2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)
Given that ΔH° = 128.9 kJ/mol and ΔG° = 33.1 kJ/mol at 25°C, above what minimum temperature will the reaction become spontaneous under standard state conditions?
◦ 0.4 K
◦ 3.9 K
◦ 321 K
◦ 401 K
◦ 525 K
