Read the following statements and choose the correct option.
$\left(\mathrm{i}\right)$ Burning of rocket fuel is accompanied by increase in entropy.
$\left(\mathrm{ii}\right)$ Melting of ice to water is characterised by increase in entropy.

What will be the molar entropy change when silver is heated from $227°\mathrm{C}$ to $727°\mathrm{C}$ ?

Consider the molar specific heat of $\mathrm{Ag},{\mathrm{C}}_{\mathrm{p}}=5.3+0.0028 \mathrm{T}$

What will be the $\Delta \mathrm{H}°$ and $\Delta \mathrm{S}°$ values for the given cell having $\text{E°}$ at $20°\mathrm{C}$ and $30°\mathrm{C}$ to be $0.18 \mathrm{V}$ and $0.28 \mathrm{V}$ respectively?

The cell: (Pt) ${\mathrm{H}}_2/{\mathrm{H}}^{+}//\mathrm{KCl}/{\mathrm{Hg}}_2{\mathrm{Cl}}_2/\mathrm{Hg}$ (Given: $1 \mathrm{F}=96500$ Coulombs)
