Freundlich adsorption isotherms for the physical adsorption of a gas at temperature \(T_1, T_2\) and \(T_3\) are shown in the graph given below. The correct relationship between \(T_1, T_2\) and \(T_3\) is
- A \(T_1 < T_2 < T_3\)
- B \(T_3 < T_1 < T_2\)
- C \(T_3 < T_2 < T_1\)
- D \(T_2 < T_1 < T_3\)
Answer & Solution
Correct Answer
(C) \(T_3 < T_2 < T_1\)
Step-by-step Solution
Detailed explanation
Lower the temperature more the adsorption. So, as the temperature increases adsorption decreases. According to Freundlich adsorption isotherm. \[ \frac{x}{m}=k \cdot p^{1 / n}(n>1) \] where, \(x\) is the mass of gas adsorbed.…
