**Consider these reactions, where M represents a generic metal.**

1. \(2 \text{M(s)} + 6 \text{HCl(aq)} \rightarrow 2 \text{MCl}_3 \text{(aq)} + 3 \text{H}_2 \text{(g)}\) 
   
   \(\Delta H_1 = -550.0 \text{ kJ}\)

2. \(\text{HCl(g)} \rightarrow \text{HCl(aq)}\) 

   \(\Delta H_2 = -74.8 \text{ kJ}\)

3. \(\text{H}_2\text{(g)} + \text{Cl}_2\text{(g)} \rightarrow 2 \text{HCl(g)}\) 

   \(\Delta H_3 = -1845.0 \text{ kJ}\)

4. \(\text{MCl}_3\text{(s)} \rightarrow \text{MCl}_3\text{(aq)}\)

   \(\Delta H_4 = -291.0 \text{ kJ}\)

**Use the given information to determine the enthalpy of the reaction**

\[ 2 \text{M(s)} + 3 \text{Cl}_2\text{(g)} \rightarrow 2 \text{MCl}_3\text{(s)} \]

\[\Delta H = \_\_\_\_\_\_ \text{ kJ}\]
