At a given temperature, the equilibrium constant for the reaction :PCl_(5)(g)hArr PCl_(3)(g)+Cl_(2)(g) is 2.4xx10^(-3). At the same temperature, the equilibrium constant for the reaction :PCl_(3)(g)+Cl_(2)(g) harr PCl_(5)(g)is :

Answer»

`2.4xx10^(-3)`
`-2.4xx10^(-3)`
`4.2xx10^(2)`
`4.8xx10^(-2)`

SOLUTION :Equilibrium CONSTANT `=(1)/(2.4xx10^(-3))`
`=4.2xx10^(2)`
