The graph given below is showing the relation between the extent of adsorption \((\mathrm{x} / \mathrm{m})\) and Pressure at different temperatures. The correct order of temperatures for curves \(\mathrm{i}\), ii and iii is
- A \(\mathrm{T}_4>\mathrm{T}_2>\mathrm{T}_3\)
- B \(\mathrm{T}_4>\mathrm{T}_3>\mathrm{T}_2\)
- C \(\mathrm{T}_2>\mathrm{T}_3>\mathrm{T}_4\)
- D \(\mathrm{T}_2>\mathrm{T}_4>\mathrm{T}_3\)
Answer & Solution
Correct Answer
(B) \(\mathrm{T}_4>\mathrm{T}_3>\mathrm{T}_2\)
Step-by-step Solution
Detailed explanation
From the graph it is obvious that the extent of adsorption \((\mathrm{x} / \mathrm{m})\) follows the order \(\mathrm{T}_2>\mathrm{T}_3>\mathrm{T}_4\). The extent of physisorption decreases with an increase in temperature. Thus, \(\mathrm{T}_4>\mathrm{T}_3>\mathrm{T}_2\).
