2. Use Hess’s Law to determine the enthalpy of the reaction below. 2F2(g) + 2H2O(l) → 4HF(aq) + O2(g) DH˚= ? H2(g) + F2(g) → 2HF(aq) DH˚ = -546.6 kJ 2H2 (g) + O2(g) → 2H2O(l) DH˚ = -571.6 kJ a. 42 kJ b. -1120 kJ c. -251 kJ d. -521 kJ e. -1690 kJ
A chemist knows that the kJ for the reaction 2H2(g) + O2 (g) ---> 2H2O (g) ,and that kJ for the reaction H2 (g) + F2 (g) ---> 2HF (g). With this information he calculated the for the reaction 2H2O (g) + 2F2 (g) ---> 4HF(g) + O2 (g) and predicted whether was positive or negative. How? A Ho- 485
