Methane reacts with steam at 1273 K in the presence of nickel catalyst to form :

Question

Accepted Answer

C. 1. **Recall the industrial process for producing hydrogen from methane**: When methane reacts with steam at high temperature in the presence of a **nickel catalyst**, it undergoes **steam reforming**, an important industrial method for the preparation of dihydrogen gas.

2. **Write the balanced reaction**: Given methane reacting with steam under these conditions,
$$
CH_4(g) + H_2O(g) \xrightarrow[1273\,K]{Ni} CO + 3H_2
$$

3. **Identify the products formed**: From the equation, the products are **CO and $H_2$**, not $CO_2$ or water.

Hence, the answer is **C. $CO$ and $H_2$**.
