Given the following equations and ΔH values, determine the heat of reaction
(kJ) at 298 K for the reaction:
B2H6(g) + 6 Cl2(g) → 2 BCl3(g) + 6 HCl(g)
BCl3(g)+ 3 H2O(l)→ H3BO3(g)+ 3 HCl(g) ΔH = -112.5 kJ
B2H6(g)+ 6 H2O(l)→ 2 H3BO3(s)+ 6 H2(g) ΔH = -493.4 kJ
½ H2(g) + ½Cl2(g) → HCl(g) ΔH = -92.3 kJ

5. Given the following equations and AH values, determine the heat of reaction
(kJ) at 298 K for the reaction:
B:Hg + 6 Clag) –→ 2 BClg + 6 HCl
BClg) + 3 H2O –→H;BO+ 3 HCle
B:Hog + 6 H2O02 H;BO0) + 6 Hz(e)
AH = -112.5 kJ
AH - -493.4 kJ
AH = -92.3 kJ
A. 1376 kJ
C. 513.6 kJ
B. -1376 kJ
D. -513.6 kJ
