Which of the following is $NOT$ an example of a secondary voltaic cell?

The standard Gibbs free energy change ($\Delta G^{\circ}$ in $kJ \, mol^{-1}$),in a $Daniell$ cell $(E^{\circ}_{cell} = 1.1 \, V)$,when $2 \, moles$ of $Zn_{(s)}$ is oxidised at $298 \, K$,is closest to

Which one of the following metals will not reduce $H_2O$?

An electrochemical cell is constructed using half-cells in the direction of spontaneous change: $Fe(OH)_{2}(s) + 2e^{-} \rightarrow Fe(s) + 2OH^{-}(aq)$ $(E^{0} = -0.88 \text{ V})$ and $AgBr(s) + e^{-} \rightarrow Ag(s) + Br^{-}(aq)$ $(E^{0} = +0.07 \text{ V})$. Which of the following options is correct?

Assertion : Galvanised iron does not rust.
Reason : Zinc has a more negative electrode potential than iron.
