JEE Main 2018 — Surface Chemistry Question with Solution
From: JEE Main 2018 (Online) 15th April Evening Slot
Question
If x gram of gas is adsorbed by m gram of adsorbent at pressure P, the plot of log versus log P is linear. The slope of the plot is :
(n and k are constants and n > 1)
(n and k are constants and n > 1)

Correct answer
D
Step-by-step explanation
According to Freundlich adsorption isotherm, in the median range of pressure
= kP
taking log both sides, we get,
log = logk + logP
Here in graph between log and logP, slope is and intercepts = log k.
= kP
taking log both sides, we get,
log = logk + logP
Here in graph between log and logP, slope is and intercepts = log k.
