Question

Assuming all volumes measured at the same temperature and pressure, state the volume ratio of the reactants and products when carbon monoxide reacting with hydrogen, forming methane and steam.

• A. 1 : 3 : 1 : 4
  
• B. 1 : 3 : 1 : 1
  
• C. 3 : 3 : 1 : 1
  
• D. 1 : 3 : 2 : 1
  

Answer 1

Answer: (B)

1 : 3 : 1 : 1

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

Stichiometry coefficient of $CO,H_2,C{H}_4,H_{2}O$ are in ratio of $1:3:1:1$

So, volume Ratio is proportional to $1:3:1:1$

Hence, the correct answer is $\left(B\right)$.
