Question 1

An exothermic reaction causes the surroundings to
◦ increase in temperature
◦ become acidic.
◦ expand.
◦ decrease in temperature.
◦ release CO2.

Question 2

At 25°C, the following heats of reaction are known:
2ClF(g) + O2(g) → Cl2O(g) + F2O(g)
ΔH°rxn =  167.4 kJ/mol
2ClF3(g)  +  2O2(g) → Cl2O(g)  +  3F2O(g)
ΔH°rxn =  341.4 kJ/mol
2F2(g) + O2(g) → 2F2O(g)
ΔH°rxn =  –43.4 kJ/mol
At the same temperature, use the above data to calculate the heat released (kJ) when 3.40 moles of ClF(g) reacts with excess F2:
         ClF(g) + F2(g) → ClF3(g)

◦ 109 kJ
◦ 233 kJ
◦ 370. kJ
◦ 465 kJ
◦ 1,580  kJ
