Fluorine is the best oxidising agent because it has

The standard electrode potential for a $Daniell$ cell is $1.1 \ V$. Calculate the standard Gibbs energy for the reaction: $[Zn_{(s)} + Cu^{2+}_{(aq)} \rightarrow Zn^{2+}_{(aq)} + Cu_{(s)}]$

Which of the following statements is false for $Hg$?

Can the absolute electrode potential of an electrode be measured?

Which of the following metals will not evolve $H_2$ gas from dilute $H_2SO_4$ solution?

The standard electrode potential $(E^o)$ of $Cu^{2+}/Cu$ is $+0.34 \, V$,while that of $Zn^{2+}/Zn$ is $-0.76 \, V$. Explain the reason for this difference.
