For the reaction :H_(2(g))+CO_(2(g))hArr CO_((g))+H_(2)O_((g)), if the initial concentraion of [H_(2)]=[CO_(2)]and x moles/litre of hydrogenis consumed at equlibrium, the correct expression of K_(p) is

Answer»

`(x^(2))/((1-x)^(2))`
`(1+x)^(2)/((1-x)^(2))`
`(x^(2))/((2+x)^(2))`
`(x^(2))/(1-x^(2))`

Solution :`H_(2(G))+CO_(2(g))hArrCO_((g))+H_(2)O_((g))`
`{:("Initial conc",1,1,0,0):}`
`{:("At eqm",(1-x),(1-x),x,x):}`
`K_(p)=(P_(CO).P_(H_(2)O))/(P_(H_(2)).P_(CO_(2)))=(x.x)/((1-x)(1-x))=(x^(2))/((1-x)^(2))`
