In the reaction below, determine x and y, and name the resulting gas mixture: CH₄(g) + H₂O(g) —1270 K, Ni→ x + y

1. x = CO₂, y = H₂O; water gas
2. x = CO, y = H₂; syngas
3. x = CO, y = H₂O; syngas
4. x = CO₂, y = H₂; syngas

Correct answer: x = CO, y = H₂; syngas

Solution

The reaction involves methane and steam at high temperature, which typically produces carbon monoxide and hydrogen gas, known as syngas. This is a common process in gasification, where methane reacts with water to yield these two products.
