Question

Carbon monoxide reacting with hydrogen, forming methane and steam.

What will be the volume ratio of the reactants and products of the given reaction?

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

Answer 1

Answer: (B)

1 : 3 : 1 : 1

Volume ratio of reactant and product in a gaseous reaction in the same as the simplest ratio of the coefficient of reactant and product in the reaction.

$CO+{3H}_2\to {CH}_4+H_{2}O$

Coefficient ratio $=1:3:1:1$

$\therefore$ Volume ratio $=1:3:1:1$

Hence, the correct option is $B$
