Question

For the reaction `PC1_(3)(g) + C1_(2)(g)hArrPC1_(5)(g)` at `250^(@)C`, the value of `K_(c)` is 26, than the value of `K_(p)` at the same temperature will be
A. `0.61`
B. 0.57
C. `0.83`
D. `0.46`

Answer 1

Correct Answer - A
`K_(p) = K_(c)(RT)^(Delta n) = 26(0.0821xx523)^(-1) = 0.61`
`Delta n_(g) = 1 - 2 = 1`
