Question

2 So2 + O2 —— 2 So3
Starting with 2 moles of So2 and 1 mole of o2 in 1 liter flask . The equilibrium mixture requires 0.4 moles of MnO4- in acidic medium the equilibrium constant is

Answer 1

Answer:

0.4 moles of kmno4 =1 mole of

so2=1mole of so3

2so2+o2_2so3

2. 1. 0

1. 0.5. 1

k=(so3)2/(so2)2 (o2)

1(1)/1(1) (0.5)

=2
