Q1 / 200 · TS EAMCET 2002 · Chemistry

$X$ litre of carbon monoxide is present at STP. It is completely oxidized to $\mathrm{CO}_2$. The volume of $\mathrm{CO}_2$ formed is 11.207 litres. What is the value of $X$ in litres?

  • A
    $22.414$
  • Correct answer
    B
    $11.207$
  • C
    $5.6035$
  • D
    $44.828$

Solution

$\begin{aligned} & \mathrm{CO}+\frac{1}{2} \mathrm{O}_2 \longrightarrow \mathrm{CO}_2 \\ & 22.4 \mathrm{~L} \quad 22.4 \mathrm{~L} \\ & x \mathrm{~L} \quad 11.207 \mathrm{~L} \\ & 22.4 \mathrm{~L} \text { of } \mathrm{CO} \text {, oxidized to } \mathrm{CO}_2=22.4 \mathrm{~L} \\ & 1 \mathrm{~L} \text { of } \mathrm{CO} \text {, oxidized to } \mathrm{CO}_2=\frac{224}{224} \mathrm{~L} \\ & \text { 11.202 L of CO, oxidized to } \mathrm{CO}_2 \\ & =\frac{224}{224} \times 11.207=11.207 \mathrm{~L} \\ & \end{aligned}$

Hence, the correct answer is option: 'B'.
