mixture of SO3, SO2 and O2 gases is maintained at equilibrium in 10 litre flask at a temp in which Kc for the reaction 2SO2 + O2 gives 2SO3. Kc= 100 .at equilibrium-
1. if no. of moles of SO3 and SO2 in flask are same then how many moles of O2 are present.
2.no. of moles of SO3 is twice of SO2, then how many moles of O2 are present.

1. We know,at equilibrium ,

       Kc[SO3]2[SO2]2[O2] = 100
As moles of SO2 is equal to that of SO3 ,
    [SO2] = [SO3]
    [O2] = 1100moles of SO3moles of SO2 = 2We again have,  Kc = [SO3]2[SO2]2 [O2] = 100  (moles of SO3moles of SO2)2(10moles of O2) = 100    22 × 10moles of O2 = 100   mole of O2 = 0.4
Mole of O210 = 1100 (vol = 10 L)   Mole of O2 = 0.1
2. Further,if moles of SO3 are twice that of  SO2,
