K(c)" for "CS(2)(g)+4H(2)(g)hArrCH(4)(g)...

`K_(c)" for "CS_(2)(g)+4H_(2)(g)hArrCH_(4)(g)+2H_(2)S(g)` is 0.28 at 900K. Calculate `K_(p)`. (R = 8.314 `JK^(-1)mol^(-1)`).

Text Solution

Verified by Experts

`CS_(2)(g)+4H_(2)(g)hArrCH_(4)(g)+2H_(2)S(g)`
`Deltan=3-5=-2`
`K_(p)=K_(c)(RT)^(Deltan)" becomes "K_(p)=K_(c)(RT)^(-2)=(0.28)/((8.314xx900)^(2))=5xx10^(-9)`.
