The incorrect statement(s) among the following statements is/are -

(i) When liquid crystallizes into a solid, entropy increases

(ii) When the temperature of a crystalline solid is raised from 0 K to 115 K then entropy increases

 $\left(iii\right) 2NaHC{O}_3 \left(s\right) \to N{a}_{2}C{O}_3 \left(s\right) + C{O}_2\left(g\right) + H_{2}O\left(g\right)$; Entropy  increases

$\left(iv\right) H_2\left(g\right) \to 2H\left(g\right)$; Entropy  decreases

1. (i), (iv)

2. (ii), (iv)

3. (iii), (iv)

4. (i), (iii)

For oxidation of iron,

 $4Fe\left(s\right) + 3O_2\left(g\right) \to 2F{e}_2{O}_3 \left(s\right)$
entropy change is -549.4 JK^-1 mol^-1 at 298 K.

(${∆}_r{H}^{\Theta }$ for this reaction is $-1648 \times {10}^3 J mo{l}^{-1}$)

The reaction is-

1. Spontaneous reaction

2. Non-spontaneous reaction

3. Reaction is an equilibrium

4. Cannot predict
