As (x/m)=k P1/n At low pressure (x/m) propto P (grap in nearly straight line) <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/910bbe4ab897d538e38f89c2254467cf-.png" /> Thus the reaction follows first order kinetics.

Q. Considering Freundlich adsorption isotherm, at low pressure, the fraction of the surface covered follows:

Zero-order kinetics

First order kinetics

Second order kinetics

Fractional order kinetics

As $\frac{x}{m} = k P^{1/ n}$
At low pressure $\frac{x}{m} \propto P$ (grap in nearly straight line)

Thus the reaction follows first order kinetics.
