If the K_(p) for the equilibrium, M.5H_(2)O(s)hArrM.3H_(2)O(s)+2H_(2)O(g) is 1xx10^(-4). Then M.5H_(2)O(s) will show efflorescence when it is exposed to an atmosphere where vapour pressure of water is

Answer»

more than `10^(-2)` atm
below `10^(-2)` atm
more than `10^(-4)` atm
below `10^(-4)` atm

SOLUTION :`K_(p)=(P_(H_(2)O))^(2)`
`P_(H_(2)O)` (at equilibrium) `=SQRT(K_(p))=10^(-2)`
Forward reaction will occur if value of `P_(H_(2)O)` is LESS than `10^(-2)` atm.
