Question

For an ideal gas reaction
`2A+BhArrC+D`
the value of `K_(p)` will be:
A. `K_(p)=(n_(C )n_(D))/(n_(A)^(2)n_(B)).V/(RT^(2))`
B. `K_(p)=(n_(C )n_(D))/(n_(A)^(2)n_(B)).V/(RT)`
C. `K_(p)=(n_(C )n_(D))/(n_(A)^(2)n_(B)).(RT)/V`
D. `K_(p)=(n_(C )n_(D))/(4n_(A)^(2)n_(B)).V/(RT)`

Answer 1

Correct Answer - B
`2A+BhArrC+D`
`K_(p)=(p_(C ).p_(D))/(p_(A)^(2).p_(B))=((n_(C )RT)/V.(n_(D)RT)/V)/(((n_(A)RT)/V)^(2).((n_(B)RT)/V))=(n_(C )n_(D))/(n_(A)^(2)n_(B)).V/(RT)`
