Given the reaction between 2 gases represented by `A_2 and B_2,` to give the compound `AB_(g)`
`A_(2(g))+B_(2(g)) Leftrightarrow 2AB_(g)`
At equilibrium, the concentration of `A_2 =3.0 xx 10^(-3) M, of B_2= 4.2 xx 10^(-3) M", of AB "=2.8 xx 10^(-3) M` If the reaction takes place in a sealed vessel at `527^@C`, then the value of `K_c` will be

A

2

B

1.9

C

0.62

D

4.5

Text Solution

Verified by Experts

The correct Answer is:
C
`A_(2(g)) +B_(2(g)) Leftrightarrow 2AB_((g))`
`K_(c)=([AB]^2)/([A_2] [B_2])=((2.8 xx 10^(-3))^2)/((3.0 xx 10^(-3)) (4.2 xx 10^(-3)))=(2.8 xx 2.8)/(3.0 xx 4.2)=0.62`
