For the reaction 2SO(2(g))+O(2(g))iff2SO...

For the reaction `2SO_(2(g))+O_(2(g))iff2SO_(3(g))` at 300 K, the value of `DeltaG^(@)` is `-690.9R`. The equilibrium constant value for the reaction at that temperature is (R is gas constant)

A

`10atm^(-1)`

B

10 atm

C

10

D

1

Text Solution

Verified by Experts

The correct Answer is:
A

`2SO_(2(g))+O_(2(g))iff2SO_(3(g))`
`DeltaG=-RTlnK`
`-690.9R=-RTlnK`
`(690.9)/(300)=lnK`
`2.303=lnK=2.303logK,K=10`
`K_(p)=(p_(SO_(3))^(2))/(p_(SO_(2))^(2).p_(O_(2)))xx(atm^(2))/(atm^(3))=atm^(-1)`
