At a certain temperature, 0.680 mol of SO3 is placed in a 3.50-L container. 2SO3 (g) <---> 2SO2(g) +O2(g) At equilibrium, 0.190 mol of O2 is present. Calculate Kc.
Here the equilibrium reaction is
initially 0.68mol of SO30 mole of SO2 + 0 mole of O2
At equilibrium
At equilibrium the moles of O2 is x=0.136moles
SO2=2x=0.272moles
SO3=0.68-2x=0.68-0.272=0.408mole
Now the solution volume is 3.5L
The concentration for is
The concetration of
The concentration of
Now for the equilibrium reaction is
Answer.
