a. `A(s) hArr A'(s)+H_(2)S(g)`
b. `B(s) hArr B'(g)+H_(2)S(g)`
At `20^(@)C` pressure over excess solid A is `50` mm and that over excess solid B is `68` mm. Find:
a. The dissociation constant of A and B
b. Relative number of moles of A' and B' in the vapour phase over a mixture of the solids A and B.
