Problem

A mixture of

SO_3

SO_2

and

O_2

gases is maintained at equilibrium in 10 litre flask at a temperature at which

K_C

for the reaction,

2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)

100 \text{ mol}^{-1} \text{ litre}

. At equilibrium. (a) If no. of mole of

SO_3

and

SO_2

in flask are same, how many mole of

O_2

are present ? (b) If no. of mole of

SO_3

in flask are twice the no. of mole of

SO_2

, how many mole of

O_2

are present ?
