Explanation / Answer

                SO2    +   NO2 --------------> NO + SO3

I            3.12       a                         0          0

C           -1.3          -1.3             1.3         1.3

E           3.12-1.3 a-1.3                      1.3    1.3    

Kc = [NO][SO3]/[SO2][NO2]

3    = 1.3*1.3/ 1.82*(a-1.3)

   3*1.82*(a-1.3) =   1.69

            a = 1.61

   no of moles of No2 is added = 1.61 moles >>>>>answer
