Answer the question on the basis of passage given below :
Adsorption is a surface phenomenon and it differs from absorption which occurs throughout the body of the substance that absorbs. In physiosorption the attractive forces are mainly van der Waal's forces while in chemisorption ionic/covalent bonds are formed between particles of adsorbent and adsorbate. The catalytic activity of finely divided iron in Haber's process of ammonia manufacture can be explained by adsorption theory. Adsorption being an exothermic process, the heat of adsorption is utilised in enhancing the rate of the reaction. Adsorption has many applications being used in gas masks, control of humidity, chromatograph separation, curing diseases etc.
Which of the following is not a surface phenomenon?

The unit's digit of \(2^{2025}\) is

If \(\left[\begin{array}{ll}3 & 1 \\ 2 & 1\end{array}\right] A\left[\begin{array}{ll}2 & 1 \\ 1 & 1\end{array}\right]=\left[\begin{array}{ll}1 & 1 \\ 0 & 1\end{array}\right]\), then matrix ' \(A\) ' is

Let the corner points of the bounded feasible region of the linear programming problem \(( LPP ) Z=a x+b y\) be \((0,0),(2,0),\left(\frac{20}{19}, \frac{45}{19}\right)\) and \((0,3)\).
If the optimal value of \(Z\) occurs at both points \((2,0)\) and \(\left(\frac{20}{19}, \frac{45}{19}\right)\), then the relation between \(a\) and \(b\) is:
