Question 1

Consider the following information:

Cl2bond energy= 239 kJ/mol

F2bond energy= 154 kJ/mol

Cl2(g) +F2(g) →ClF3(g)

ΔH° = –409 kJ/mol

Calculate the Cl-F bond energy given this information.


267 kJ/mol
253 kJ/mol
760 kJ/mol
136 kJ/mol
None of these are correct.

Question 2

Consider the following numbered processes:
1.
A → 2B
2.
B → C + D
3.
E → 2D
ΔH for the process A → 2C + E is:


ΔH1 + ΔH2 + ΔH3.


ΔH1 + ΔH2.


ΔH1 + ΔH2- ΔH3.


ΔH1 + 2ΔH2- ΔH3.


ΔH1 + 2ΔH2 + ΔH3.
