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)

Answer»

`10ATM^(-1)`
10 atm
10
1

Solution :`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)`
