5 moles of SO(2)and 5 moles of O(2) are ...

5 moles of `SO_(2)`and 5 moles of `O_(2)` are allowed to react .At equilibrium , it was foumnd that `60%` of `SO_(2)` is used up .If the pressure of the equilibrium mixture is one aatmosphere, the parital pressure of `O_(2)` is :

A

0.82atm

B

0.52atm

C

0.21atm

D

0.41atm

Text Solution

Verified by Experts

The correct Answer is:
D
`SO_(2) + 1/2O_(2) rarr SO_(3)`
Total moles of equilibrium = `2 + 7/2 + 3 = 17/2 implies P_(O_(2)) = 0.4 atm`
