From equation (i) and (ii),
`CO_2hArrCO+(1)/(2)O_(2)[K_(c1)=9.0xx10^(-12)` at `1000^(@)C]` (i)
`H_(2)OhArrH_(2)+(1)/(2)O_(2)[K_(c2)=7.0xx10^(-12)` at `1000^(@)C]` (ii)
the equilibrium for the reaction
`CO_(2)+H_(2)hArrCO+H_(2)O`
at the same temperature is

A

`0.78`

B

`2.0`

C

`16.2`

D

`1.28`

Text Solution

Verified by Experts

The correct Answer is:
D
(i) `CO_(2) hArr CO + 1/2O_(2) K_(1) = 9.1 xx 10^(-13)`
(ii) `H_(2)O hArr H_(2) + 1/2 O_(2)K_(2) = 7.1 xx 10^(-12)`
Object `CO_(2) + H_(2) hArr CO + H_(2)O`
equation (i) - (ii)
`:. K^(1) = (K_(1))/(K_(2)) = 1.28`
`C_(t) = C_(0)e^(-kt)`
`:. R = R_(0)e^(-kt)`
