The product of the reaction between steam and Hydrocarbon in presence of Ni catalyst at 900°C is _____.
Correct answer: B. CO+H²(water gas)
- A. CO²+O²
- B. CO+H²(water gas)
- C. CO³+H²O
- D. Laughing Gas
Explanation
Steam reforming of a hydrocarbon such as methane over nickel at about 900 °C gives carbon monoxide and hydrogen: CH4 + H2O → CO + 3H2. The likely distractor is carbon dioxide and oxygen, but steam reforming does not produce oxygen and the product mixture is commonly called water gas.

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
