Which of the following reaction corresponds to the definition of enthalpy of combustion at 25°C?
- \(\mathrm{CH}_{4}(\mathrm{~g})+\mathrm{ZO}_{2}(\mathrm{~g}) \rightarrow \mathrm{CO}_{2}(\mathrm{~g})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{l})\)
- \(\mathrm{CH}_{4}(\mathrm{~g})+2 \mathrm{O}_{2}(\mathrm{~g}) \longrightarrow \mathrm{CO}_{2}(\mathrm{~g})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{~g})\)
- \(\mathrm{CH}_{4}(\mathrm{O})+\mathrm{ZO}_{2}(\mathrm{~g}) \longrightarrow \mathrm{CO}_{2}(\mathrm{~g})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{~g})\)
- \(\mathrm{CH}_{4}(\mathrm{O})+\mathrm{ZO}_{2}(\mathrm{O}) \longrightarrow \mathrm{CO}_{2}(\mathrm{O})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{O})\)
Answer
(A) CH _ 4 ( ~g )+ ZO _ 2 ( ~g ) CO _ 2 ( ~g )+2 H _ 2 O ( l )
