Find the value of `K_(p)` for the reaction : `2SO_(2)(g)+O_(2)(g) hArr 2SO_(3)(g)`, if the partial pressures of `SO_(2), O_(2)`, and `SO_(3)` are 0.559 atm, 0.101 atm and 0.331 atm respectively. What will be the partial pressure of `O_(2)` gas if at equilibrium, equal amounts (in moles) of `SO_(2) and SO_(3)` are observed?

Options

A. 0.5 atm
B. 0.3 atm
C. 0.2 atm
D. 0.1 atm

Answer

C

Explanation

`2SO_(3(g)) Leftrightarrow 2SO_(2(g))+O_(2(g))`
`"t=0 1 0 0"`
`"at eq 1-2x 2x x"`
2x=0.5
`P_(SO_(3))=P xx X_(SO_(3))`
