The values of for the reactions,

X $$\rightleftharpoons$$ Y + Z      . . . .(i)
A $$\rightleftharpoons$$ 2B       . . . .(ii)

are in the ratio 9 : 1. If degree of dissociation of X and A be equal, then total pressure at equilibrium (i) and (ii) are in the ratio

The value of equilibrium constant of the reaction
HI_(g) $$\rightleftharpoons$$ $${1 \over 2}$$H_2(g) + $${1 \over 2}$$I_2(g)
