Question

What is the numerical value of KcKc for the reaction if the concentrations at equilibrium are 0.10 MM SO2SO2, 0.18 MM O2O2, and 0.66 MM SO3SO3 ? 2SO2(g)+O2(g)⇌2SO3(g)

Answer 1

Numerical value of
`K_(c)` is 242

Step-by-step explanation:

`K_(c)` for the given reaction is represented as-

`K_(c)=([SO_(3)]^(2))/([SO_(2)]^(2)[O_(2)])`

Where species inside third bracket represent equilibrium concentrations.

Here,
`[SO_(3)]=0.66M` ,
`[SO_(2)]=0.10M` and
`[O_(2)]=0.18M`

Plug-in all the given values in the above equation-

`K_(c)=((0.66)^(2))/((0.10)^(2)* (0.18))`

`=242`

So, numerical value of
`K_(c)` is 242
