# Calculate $\Delta H$ in kJ for the following reaction : $C_{(s)}+O_{2(g)} \longrightarrow CO_{2(g)}$ Given that , $H_2 O_{(g)} + C_{(s)} \longrightarrow CO_{(g)} + H_{2(g)} +H_{2(g)} \quad \Delta H =+131\;kJ$ $CO_{(g)}+\large\frac{1}{2} O_{2(g)} \longrightarrow CO_{2(g)} \qquad \Delta H =-282\;kJ$ $H_{2(g)}+\frac{1}{2} \;O_{2(g)} \longrightarrow H_2O_{(g)} \qquad \Delta H =-242\;kJ$

$\begin {array} {1 1} (1)\;-393 & \quad (2)\;+393 \\ (3)\;+655 & \quad (4)\;-655 \end {array}$

(1) -393
