\( P \)
(a) C (g) \( +4 \mathrm{H} \) (g) \( \longrightarrow \mathrm{CH}_{4}(\mathrm{~g}) ; \quad \Delta_{\mathrm{r}} \mathrm{H}=\mathrm{x} \mathrm{kJ} \mathrm{mol}^{-1} \)
(b) C (graphite,s) \( +2 \mathrm{H}_{2}(\mathrm{~g}) \longrightarrow \mathrm{CH}_{4}(\mathrm{~g}) ; \quad \Delta_{\mathrm{r}} \mathrm{H}=\mathrm{y} \mathrm{kJ} \mathrm{mol}^{-1} \)
W.
(A) \( x=y \)
(B) \( x=2 y \)
