Question

$5$ moles of $SO_2$ and $5$ moles of $O_2$ are allowed to react. At equilibrium, it was found that $60\%$ of $SO_2$ is used up. If the partial pressure of the equilibrium mixture is one atmosphere, the partial pressure of $O_2$, is

• A. 0.21 atm
• B. 0.41 atm
• C. 0.82 atm
• D. 0.52 atm

Answer 1

Answer: (B)

0.41 atm

Answer 2

$\therefore \,\,\,\,\,\,p O _{2}=\frac{3.5 \times 1}{8.5}=0.41 \,atm$
