If $\quad C$ (diamond $) \rightarrow C$ (graphite $)+\mathrm{X} \mathrm{kJ} \mathrm{mol}^{-1}$
$\mathrm{C}($ diamond $)+\mathrm{O}_2(\mathrm{~g}) \rightarrow \mathrm{CO}_2(\mathrm{~g})+\mathrm{Y} \mathrm{kJ} \mathrm{mol}^{-1}$
C (graphite) $+\mathrm{O}_2(\mathrm{~g}) \rightarrow \mathrm{CO}_2(\mathrm{~g})+\mathrm{Z} \mathrm{kJ} \mathrm{mol}^{-1}$
at constant temperature. Then
  1. X=-Y+Z
  2. -X=Y+Z
  3. X=Y+Z
  4. X=Y-Z
