Question
Given the following equations and AH° values, determine the heat of reaction (kJ) at
298 K for the reaction:
B,He(g) + 6 Cl2(g)
->
2 BCI,(g) + 6 HCI(g)
BCI,(g) + 3 H,O(1)
B2H6(g) + 6 H20(1)
1/2 H2(g) + 1/2 Cl2(g)
H;BO3(g) + 3 HCI(g)
2H;BO,(s) + 6 H2(g)
AH/kJ = -112.5
AHO/kJ = -493.4
AHO/kJ = -92.3
HCI(g)
