Gas + Solid? GS? H = -ve
Adsorbed gas
Adsorption of gas is an exothermic process. Increase in temperature reduces the extent of adsorption.

$\mathrm{}{f}^{\mathrm{\text{'}}}\left(x\right)=x\left(\pi -{\mathrm{c}\mathrm{o}\mathrm{s}}^{-1}?(\mathrm{s}\mathrm{i}\mathrm{n}?|x\left|\right)\right)=x\left(\pi -\left(\frac{\pi }{2}-{\mathrm{s}\mathrm{i}\mathrm{n}}^{-1}?(\mathrm{s}\mathrm{i}\mathrm{n}?|x\left|\right)\right)\right)=x\left(\frac{\pi }{2}+\left|x\right|\right)$

$f\left(x\right)=\left\{\begin{array}{ll}x\left(\frac{\pi }{2}+x\right)& x\ge 0\\ x\left(\frac{\pi }{2}-x\right)& x<0\end{array}\right.$

$f^{\mathrm{\text{'}}}\left(x\right)=\left\{\begin{array}{ll}\frac{\pi }{2}+2x& x\ge 0\\ \frac{\pi }{2}-2x& x<0\end{array}\right.$  is increasing in $f^{\mathrm{\text{'}}}\left(x\right)$ ${}^{}$ and decreasing in $\left(0,\frac{\pi }{2}\right)$

In FCC octahedral voids are present at the edge centers and body center

Consider a diagonal projected form edge centre passing through the body centre
Distance between octahedral voids = √2a/2 = a/√2

δ_min = (µ - 1)A
= (1.5 - 1)1
= 0.5
δ_min = 5/10

$\mathrm{}\pm 1=\left|\begin{array}{lll}1& 1& \lambda \\ 1& 1& 3\\ 2& 1& 1\end{array}\right|\Rightarrow =-\lambda +3=\pm 1$ or $\Rightarrow \lambda =2$

For $\lambda =4$ $$

$\lambda =4$

$\mathrm{c}\mathrm{o}\mathrm{s}?\theta =\frac{2+1+4}{\sqrt[]{6}\sqrt[]{18}}=\frac{7}{6\sqrt[]{3}}$

E? = φ + K?
E? = φ + K?
E? - E? = K? - K?
Now V? /V? = 2
K? /K? = 4; K? = 4K?
Now from equation (2)
⇒ 4 - 2.5 = 4K? - K?
1.5 = 3K?
K? = 0.5eV
Now putting this
Value in equation (2)
2.5 = φ + 0.5eV
φ = 2eV

Let us assume the potential at A = V_A = 0.
Now at junction C, according to KCL
i? + i? = i?
1 A + i? = 2 A

i? = 2 A
Now analyse potential along ACDB
V_A + 1 + i? (2) - 2 = V_B
0 + 1 + 2 (1) - 2 = V_B
V_B = 3 - 2
V_B = 1amp.

Figure of Merit = C = i/θ

x = 1/√ (µ? ε? ) = speed ⇒ [x] = [L¹T? ¹]
y = E/B = speed ⇒ [y] = [L¹T? ¹]
z = l/ (RC) = l/τ ⇒ [z] = [L¹T? ¹]
So, x, y, z all have the same dimensions.

$\mathrm{}E=E_0-\frac{0.0591}{4}\mathrm{l}\mathrm{o}\mathrm{g}?{\left. [{\mathrm{H}}^{+}\right]}^4$

$\mathrm{E}=1.23+0.0591*\mathrm{p}\mathrm{H}$

$E=1.23+0.0591*\left(5\right)$

$E=1.52$
