Concept:Steam reforming of methane produces synthesis gas (syngas), a mixture of carbon monoxide and hydrogen.Chemical Equation / Formula:$\mathrm{CH}_4(\mathrm{g}) + \mathrm{H}_2\mathrm{O}(\mathrm{g}) \xrightarrow[\mathrm{Ni}]{1273\ \mathrm{K}} \mathrm{CO}(\mathrm{g}) + 3\mathrm{H}_2(\mathrm{g})$Explanation:Methane ($\mathrm{CH}_4$) reacts with steam ($\mathrm{H}_2\mathrm{O}$) at a high temperature of 1273 K over a nickel (Ni) catalyst.This is an endothermic reaction used industrially to produce dihydrogen ($\mathrm{H}_2$).The products are carbon monoxide ($\mathrm{CO}$) and three molecules of hydrogen gas.Thus, the correct product pair is $\mathrm{CO}$ and $\mathrm{H}_2$.Shortcut:This process is known as steam reforming of methane. The product mixture ($\mathrm{CO} + \mathrm{H}_2$) is called synthesis gas or syngas, which is a key industrial feedstock.Answer:Option C: $\mathrm{CO}$ and $\mathrm{H}_2$
