Question

Carbon monoxide reacting with hydrogen, forming methane and steam. The volume ratio of reactants to products is:

• A. 2 : 3 : 2 : 1
• B. 1 : 3 : 1 : 2
• C. 1 : 3 : 1 : 1
• D. 2 : 1 : 1 : 1

Answer 1

Answer: (C)

1 : 3 : 1 : 1

The equation for the reaction of carbon monoxide and hydrogen to form methane and water is written as:

$CO+3H_2\to C{H}_4+H_{2}O$

Therefore, the volume ratio of reactants and products $=1:3:1:1$.

Hence, option C is correct.
