Question

What is the chemical reaction for the production of carbon monoxide and hydrogen gases when steam (gaseous water) reacts with carbon at high temperatures?

a) H2O + C → CO + H2

b) CO2 + H2 → CO + H2O

c) H2O + CO → C + H2

d) CO + C → H2O + H2

Answer 1

The correct chemical reaction for producing carbon monoxide and hydrogen gas from steam and carbon is H2O(g) + C(s) → CO(g) + H2(g), which is the process used in the industrial production of water gas.

Step-by-step explanation:

The chemical reaction for the production of carbon monoxide (CO) and hydrogen gas (H2) when steam (gaseous water) reacts with carbon at high temperatures is represented by the equation given in options. The correct option that represents this reaction is a) H2O(g) + C(s) → CO(g) + H2(g). This is a well-known industrial process used to produce a fuel known as water gas.

The b), c), and d) options do not correctly represent the reaction between steam and carbon to produce carbon monoxide and hydrogen gas. Option b) represents the water-gas shift reaction where carbon monoxide reacts with water to form carbon dioxide and more hydrogen. Option c) and d) do not represent the reaction of carbon with steam.
