At 700 K, the equlibrium constant K_(p) for the reaction 2SO_(3(g))hArr2SO_(2(g))+O_(2(g))is 1.80xx10^(-3) and kP_(a) is 14, (R=8.314,Jk^(-1)mol^(-1)). The numerical value in moles per litre of K_(c) for this reaction at the same temperatue will be

Answer»

`8.18xx10^(-9)"mol-litre"`
`5.07xx10^(-8)"mol-litre"`
`8.18xx10^(-9)"mol-litre"`
`9.24xx10^(-10)"mol-litre"`

Solution :`UNDERSET(2)(2SO_(3))hArr2SO_(2)underset(2)(+)O_(2)`
`DELTAN=3-1=+1,K_(p)=1.80xx10^(-3)`
`[RT]^(Deltan)=(8.314xx700)^(1)`
`K_(c)=(K_(p))/((RT)^(Deltan))=(1.8xx10^(-3))/((8.314xx700)^(1))`
`=3.09xx10^(-7)"mole-litre."`
