Q. A schematic representation of enthalpy changes for the $C_{\text{(graphite)}} + \frac{1}{2}O_2(g) \to CO(g)$ reaction, is given below. The missing value isChemistry Question Image

Thermodynamics

Solution:

Since enthalpy is state function,
$ΔH + (- 283.0 \,kJ) = - 393.5 \,kJ$
or, $ΔH = - 110.5 \,kJ$
