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: Ratio of K_(p) for reaction (i) to that of reaction (ii), is:

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: Ratio of K_(p) for reaction (i) to that of reaction (ii), is:
Answer» `4:9` `2:3` `4:9` `2:1` SOLUTION :`{:(X(s),hArr,A(G),+,C(g),),(,,20 mm,,20 mm):}` `K_(P_(1))=20xx20=400 mm^(2)` and `{:(Y(s),hArr,B(g),+,C(g),),(,,30 mm,,30 mm):}` `K_(P_(2))=30xx30=900 mm^(2)` `:. K_(p_(1))/K_(p_(2))=4/9`
