$-108.7\text{ kJ}$

Work Step by Step

We combine the following reactions: $ClF_{(g)}+\frac{1}{2}O_{2(g)}\Rightarrow \frac{1}{2}Cl_2O_{(g)}+\frac{1}{2}F_2O_{(g)}\text{ 83.7 kJ}$ $\frac{1}{2}Cl_2O_{(g)}+\frac{3}{2}F_2O_{(g)}\Rightarrow ClF_{3(g)}+O_{2(g)}\text{ -170.7 kJ}$ $F_{2(g)}+\frac{1}{2}O_{2(g)}\Rightarrow F_2O_{(g)}\text{ -21.7 kJ}$ $\Delta E = 83.7-170.7-21.7=-108.7\text{ kJ}$
