2. Given the following data \[ \begin{array}{l} 2 \mathrm{ClF}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{Cl}_{2} \mathrm{O}(\mathrm{~g})+\mathrm{F}_{2} \mathrm{O}(\mathrm{~g}) \\ 2 \mathrm{ClF}_{3}(\mathrm{~g})+2 \mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{Cl}_{2} \mathrm{O}(\mathrm{~g})+3 \mathrm{~F}_{2} \mathrm{O}(\mathrm{~g}) \\ 2 \mathrm{~F}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightarrow 2 \mathrm{~F}_{2} \mathrm{O} \end{array} \] \[ \begin{array}{l} \Delta \mathrm{H}=167.4 \mathrm{~kJ} \\ \Delta \mathrm{H}=341.4 \mathrm{~kJ} \\ \Delta \mathrm{H}=-43.4 \mathrm{~kJ} \end{array} \] Calculate \( \Delta \mathrm{H} \) for the reaction \[ \mathrm{ClF}(\mathrm{~g})+\mathrm{F}_{2}(\mathrm{~g}) \rightarrow \mathrm{ClF}_{3}(\mathrm{~g}) \] What is the theoretical basis of your calculation? In other words, which law is your calculation based on?

          2. Given the following data
\[
\begin{array}{l}
2 \mathrm{ClF}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{Cl}_{2} \mathrm{O}(\mathrm{~g})+\mathrm{F}_{2} \mathrm{O}(\mathrm{~g}) \\
2 \mathrm{ClF}_{3}(\mathrm{~g})+2 \mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{Cl}_{2} \mathrm{O}(\mathrm{~g})+3 \mathrm{~F}_{2} \mathrm{O}(\mathrm{~g}) \\
2 \mathrm{~F}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightarrow 2 \mathrm{~F}_{2} \mathrm{O}
\end{array}
\]
\[
\begin{array}{l}
\Delta \mathrm{H}=167.4 \mathrm{~kJ} \\
\Delta \mathrm{H}=341.4 \mathrm{~kJ} \\
\Delta \mathrm{H}=-43.4 \mathrm{~kJ}
\end{array}
\]

Calculate \( \Delta \mathrm{H} \) for the reaction
\[
\mathrm{ClF}(\mathrm{~g})+\mathrm{F}_{2}(\mathrm{~g}) \rightarrow \mathrm{ClF}_{3}(\mathrm{~g})
\]

What is the theoretical basis of your calculation? In other words, which law is your calculation based on?

2. Given the following data

2 ClF( g)+O2( g) →Cl2O( g)+F2O( g)

2 ClF3( g)+2 O2( g) →Cl2O( g)+3 F2O( g)

2 F2( g)+O2( g) → 2 F2O

ΔH=167.4 kJ
ΔH=341.4 kJ
ΔH=-43.4 kJ

Calculate ΔH for the reaction

ClF( g)+F2( g) →ClF3( g)

What is the theoretical basis of your calculation? In other words, which law is your calculation based on?
