Which of the following are correct about the reaction ` A + 2B hArr C + D `

Options

A. `K_p=(n_C xx n_D)/(n_A xx (N_B)^2) xx ((P)/(RT))^(-1)`
B. `K_P=(n_C xx n_D)/(n_A xx (n_B)^2) xx ((P)/(Sigma n))^(-1)`
C. `K_p=(n_C xx n_D)/(n_A xx (n_B)^2) xx ((V)/(RT))`
D. `K_C=([C][D])/([A][B]^2)`

Answer

B, C, D

Explanation

`K_(C)=([C][D])/([A][B]^(2))=(n_(C))/(n_(A))(n_(D))/(n_(B)^(2)) xx V, K_(P)=K_(C)(RT)^(-1)`
`=(n_(C)n_(D))/(n_(A)n_(B)^(2))((V)/(RT))=(n_(C)n_(D))/(n_(A)n_(B)^(2))((sum n)/(P))`
