The adsorption isotherm for a gas is given by the relation x=a p /(1+b p) where x is moles of gas adsorbed per gram of the adsorbent, p is the pressure of the gas, and a and b are constants. Then x
Options
- Aincreases with p
- Bremains unchanged with p
- Cdecreases with p
- Dincreases with p at low pressures and then remains the same at high pressure
Correct answer
D. increases with p at low pressures and then remains the same at high pressure
Step-by-step solution
According to Lagmuir curve x = ap 1+ bp array ll p & x = a b p 0 & x p array
