A vessel at 1000K contains `CO_2` with a pressure of 0.5 atm. Some of the `CO_2` is converted into CO on the addition of graphite. If the total pressure at equilibrium is 0.8atm. The value of K is

A

3 atm

B

0.3 atm

C

0.18 atm

D

1.8 atm

Text Solution

Verified by Experts

`underset(0.5-x)(CO_2(g)+C(s))
`0.5-x+2x=0.8`
or x=0.3, K=`(p^2co)/(pco_2)=((0.6)^2)/(0.2)=1.8atm`

At a given temperature, a closed vessel contains NH_3 gas and solid NH_4HS . The pressure of NH_3 gas in the vessel is 0.50 atm. On dissociation, NH_4HS produces NH_3 and H_2S gases. The total pressure in the flask at equilibrium is 0.84 atm. The equilibrium constant for the dissociation reaction (KP) of NH_4HS is-

A 20 litre container at 400 K contains CO_2 (g) at pressure 0.4 atm and an excess of SrO (neglect the volume of solid SrO). the volume of the container is now decreased by moving the movable piston fitted in the container. The maximum volume of the container, when pressure of CO_2 attains its maximum value, will be- (Given that: SrCO_3(s) K_p =1.6 atm
