Question

If $10$ liters of CO gas react with sufficient amount of oxygen for a complete reaction, how many liters of $C{O}_2$ gas will be formed?

• A. $5$
• B. $10$
• C. $15$
• D. $20$
• E. $40$

Answer 1

Answer: (B)

$10$

$2CO+O_2\to 2C{O}_2$

From the balanced equation for the combustion reaction, we can say that the number of moles of $C{O}_2$ formed is equal to the number of moles of $CO$ reacted.

Also, volume of a gas is directly proportional to the number of moles.
Hence, the volume of $C{O}_2$ formed is equal to the volume of $CO$ reacted.

Hence, if 10 liters of $CO$ gas react with sufficient amount of oxygen for a complete reaction, 10 liters of $C{O}_2$ gas will be formed.

Hence, the correct answer is option $\text{B}$.
