The equilibrium constant for the reaction,
HI(g) is Kc
Equilibrium constant for the reaction 2HI(g) H2(g) + I2(g) will be
1/Kc
1/(Kc)2
2/Kc
2/(Kc)2
B.
1/(Kc)2
The given reaction is,
...(i)
Hence, ...(ii)
Now, reverse the equaion (i) and multiple by 2, we get
Equating equations (ii) and (iii), we get
