1.	Two solids X and Y dissociate into gaseous products at a certain temperature as follows: i. X(s) hArr A(g)+C(g) and ii. Y(s) hArr B(g)+C(g) At a given temperature, pressure over excess solid 'X' is 40 mm of Hg and total pressure over solid 'Y(s)' is 60 mm of Hg. Now, answer the following questions: The total pressure of gaseous over a mixture of solids X and Y is:
Answer» `100` mm `74.84` mm `50` mm `120.74` mm Solution :`K_(p_(1))=p_(1)(p_(1)+p_(2))` `K_(p_(2))=p_(2)(p_(1)+p_(2))` On solveing `p_(1)=23.09, p_(2)=51.75` `:. p_(1)+p_(2)=74.84 mm` Hence, (b) is the correct ANSWER.
