The adsorption isotherm for a gas is given by the relation `x=ap//(1+bp)` where x is mole of gas adsorbed per gram of the adsorbent, p is the pressure of the gas, and a and b are constants. Then x

A

increases with p

B

remains unchanged with p

C

decreases with p

D

increases with p at low pressures and then remains the same at high pressure

Text Solution

Verified by Experts

The correct Answer is:
D
According to Lagmuir curve
`x=(ap)/(1+bp)`
`p rarr oo" "x=a/b`
`p rarr 0" "x prop p`
