Solution

Explanation:

In chemisorption, the adsorption amount initially rises with temperature due to activation energy requirements, then falls as desorption dominates, producing a peak-shaped graph of `x/m` vs. T. This behaviour is characteristic of chemisorption adsorption isobars at constant pressure.
