Question 1

Consider the following processes:
 
ΔH (kJ/mol)
3B → 2C + D    
–125.
(1/2)A → B
150
E + A → D
350
Calculate ΔH for: B → E + 2C


325 kJ/mol
525 kJ/mol
–175 kJ/mol
–325 kJ/mol
none of these are correct

Question 2

Consider the following processes:
2A → (1/2)B + C
ΔH1 = 5 kJ/mol
(3/2)B + 4C → 2A + C + 3D
ΔH2 = –15 kJ/mol
E + 4A → C
ΔH3 = 10 kJ/mol
Calculate ΔH for:     C → E + 3D


0 kJ/mol
10 kJ/mol
–10 kJ/mol
–20 kJ/mol
20 kJ/mol
