The following equilibrium constants were determined at 1120k :
`2CO_((g)) hArr C_((s)) + CO_(2(g)) , Kp_(I) = 10^(-14) atm^(-1) , CO_((g)0 + Cl_(2(g)) hArr COCl_(2(g)) , Kp_(2) = 6 xx 10^(-3) atm^(-1)`
What is the equilibrium constant Kc for the following reaction at 1120K:
`C_((s)) + CO_(2(g)) + 2Cl_(2(g)) hArr 2CO_(2) Cl_((g))`

A

`3.31 xx 10^(11) M^(-1)`

B

`5.5 xx 10^(10) M^(-1)`

C

`5.51 xx 10^(6) M^(-1)`

D

`3.31 xx 10^(11) M`

Text Solution

Verified by Experts

The correct Answer is:
A
Resultant `Kp=((Kp_(2))^(2))/(Kp_(1))=36 xx 10^(8)`
`implies Kp=Kc(RT)^(Delta n) implies Kc=3.3 xx 10^(11)M`
