The equilibrium constant KC for the reaction below has a value of 2.80 x 10^2 at a certain temperature. Suppose that for a particular system at equilibrium at that certain temperature the SO2 molar density is 0.0124 mol/L and the O2 molar density is 0.0310. Please predict the molar density of SO3.
2SO2 (g) + O2 (g) →2SO3 (g)
Let we have a equilibrium reaction as

then the equilibrium constant
of the above
equilibrium reaction is written as

Here the Equilibrium reaction is written as


As we know that
of the above
equilibrium reaction is written as

We have the given concentration as



Now by using the law


Hence the concentration of
at
equilibrium is found as 0.0362M.
