K p =(( P SO 3)2/( P SO 2)2( P O 2)) =((0.331)2/(0.662)2(0.101))=2.5 Now K p =(( P SO 3)2/( P SO 2)2( P O 2)) If PSO3=PSO2 Then, P O 2=(1/ K p ) =(1/2.5)=0.4 atm

Q. In the equilibrium, 2SO2(g)​+O2(g)​⇌2SO3(g)​) the partial pressure of SO2​,O2​ and SO3​ are 0.662, 0.101 and 0.331 atm respectively. What should be the partial pressure of oxygen so that the equilibrium concentration of SO2​ and SO3​ are equal ?

0.4 atm

1.0 atm

0.8 atm

0.25 atm

Kp​=(PSO2​​)2(PO2​​)(PSO3​​)2​ =(0.662)2(0.101)(0.331)2​=2.5 Now Kp​=(PSO2​​)2(PO2​​)(PSO3​​)2​ If PSO3​​=PSO2​​ Then, PO2​​=Kp​1​ =2.51​=0.4atm

Q. In the equilibrium,
$2 S O_{2 (g)} + O_{2 (g)} ⇌ 2 S O_{3 (g)})$
the partial pressure of $S O_{2}, O_{2}$ and $S O_{3}$ are $0.662$ , $0.101$ and $0.331$ atm respectively. What should be the partial pressure of oxygen so that the equilibrium concentration of $S O_{2}$ and $S O_{3}$ are equal ?
