Question

Name the gas produced when hydrocarbons(alkanes) react with steam.

• A. only $H_2$
• B. both $CO\text{and}{H}_2$
• C. $C{O}_2$
• D. All of the above.

Answer 1

The correct option is B both $CO\text{and}{H}_2$

Hydrocarbons (alkanes) react with steam at high temperature to produce carbon monoxide and hydrogen.
$C{H}_4\left(gas\right)+H_{2}O\left(gas\right)\underset{catalyst}{\overset{1270K}{\to }}CO\left(gas\right)+3H_2$
