Which equation is true Langmuir adsorption isotherm at low pressure?

Answer»

<P>`(x)/(m)=(1)/(n)XXP`
`(x)/(m)=ap`
`(x)/(m)=(b)/(a)`
`(x)/(m)=(a)/(b)`

Solution :`(x)/(m)=ap`
For Langmuir adsorption `(x)/(m)=(ap)/(1+bp)`
If PRESSURE is lower then, p = 0
`therefore""bp=0`
`therefore""1+bp=1`
`therefore""(x)/(m)=(ap)/(1+bp)=(ap)/(1)` So, OPTION (B) is RIGHT
