In the system, `LaCI_(3(s)) + H_(2)O(g)` `rarr` LaCIO(s) + 2HCI(g) - heat , equililbrium is established. More water vapour is added to restablish the equilibrium. The pressure of water vapour is doubled. The factor by which pressure of HCI is changed is

A

`2`

B

`sqrt2`

C

`sqrt3`

D

`sqrt5`

Text Solution

Verified by Experts

The correct Answer is:
B
`LaCI_(3)(s)+H_(2)O(g)+"heat"toLaCIO(s)+2HCI(g)`
`K_(P)=(P_(HCI)^(2))/(P_(H_(2)O))=P_(HCI)^(,2)/(2P_(H_(2)O))=P_(HCI)=sqrt2 P_(HCI)`

( i ) The equilibrium H_(2(g))+CO_(2(g))hArrH_(2)O_(2(g))+CO_((g)) is established in an evacuated vessel at 723 K starting with 0.1 mol of H_(2) and 0.2 mole of CO_(2) . If the equilibrium mixture contains 10 mole per cent of water vapour, calculate K_(p) , given that the equilibrium pressure is 0.5 atm . Calculate the partial pressures of the component species and the volume of the container. ( ii ) If now, into the flask, solid CoO and solid Co are introduced two new equilibrium are established. CoO_((s))+H_(2(g))hArrCo_((s))+H_(2)O_((g)) , CoO_((s))+CO_((g))hArrCo_((g))+CO_(2(g)) The new equilibrium mixture contains 30 mole per cent of water vapour. Calculate the equilibrium constants for the new equilibria.
