$C ( s )+\frac{1}{2} O _{2}( g ) \rightarrow CO ( g )+100 \;kJ$
When coal of purity $60 \%$ is allowed to burn in presence of insufficient oxygen, $60 \%$ of carbon is converted into $'CO'$ and the remaining is converted into $'CO _{2}$$'$.
The heat generated when $0.6 \;kg$ of coal is burnt is
$ H_2(g) + Cl_2(g) \to 2HCl(g), \Delta H^o = -185\, kJ$
What is $\Delta U^o$ for this reaction? .....$kJ$
