For the phenomenon of adsorption, the correct statement or statements among the following is or are

According to Freundlich model, mass of $$\text{N}_2$$ gas adsorbed per g of silica surface will increase with temperature of adsorption

If S is the surface area of an adsorbent, and A, m and M are the cross-sectional area, mass adsorbed and molar mass of the adsorbate respectively, then $$S = \frac{m}{M} A N_A$$, where $$N_A$$ is Avogadro's number

The number of gas molecules physisorbed on unit mass of an adsorbent will be the same for two different gases at the same temperature

Adsorption of $$\text{H}_2$$ on Ni surface with $$E_a = 96$$ kJ $$\text{mol}^{-1}$$ can be termed as chemisorption
