Given that the equilibrium constant for the reaction 2SO_(2)(g)+O_(2)(g)hArr2SO_(3)(g) has a value of 270 at a particular temperaturee. What is the vlaue of the equilibrium constant for the following reaction at same temperaturee SO_(3)(g)hArrSO_(2)(g)+1/2O_(2)(g)

Answer»

`1.8xx10^(-3)`
`3.6XX10^(-3)`
`6.0xx10^(-2)`
`1.3xx10^(-5)`

SOLUTION :`2SO_(2)(G)+O_(2)(g)hArr2SO_(3)(g)`
`SO_(3)(g)hArrSO_(2)(g)+1/2O_(2)(g)`
`K=278`
`K=1/K=sqrt((1)/(278))=sqrt(35.97xx10^(-4))=6xx10^(-2)`
