Consider the reaction
$2\text{H}_2\text{S}(g) + 3\text{O}_2(g) \rightarrow 2\text{H}_2\text{O}(l) + 2\text{SO}_2(g)$
The magnitude of enthalpy change for the reaction in kJ mol$^{-1}$ is ________. (Nearest integer)
Given: $\Delta_fH^{\ominus}(\text{H}_2\text{S}) = -20.1$ kJ mol$^{-1}$
$\Delta_fH^{\ominus}(\text{H}_2\text{O}) = -286.0$ kJ mol$^{-1}$
$\Delta_fH^{\ominus}(\text{SO}_2) = -297.0$ kJ mol$^{-1}$
