Statement $I:$ According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increases with decrease in positive charges on the nucleus as there is no strong hold on the electron by the nucleus.
Statement $II:$ According to Bohr's model of an atom, qualitatively the magnitude of velocity of electron increases with decrease in principal quantum number.
In the light of the above statements, choose the most appropriate answer from the options given below:
$| Pt(s)$ At $298\ K$, $E^o_{cell}$ for cell is $- 2.31\ V$ , what will be the $E_{cell}$ at $pH = 1$ ? ........... $\mathrm{Volt}$
$Zn(s) + Cu^{2+}(M) \to Zn^{2+}(M') + Cu(s);$ $E^o _{cell} = 1.10\,V$
$X$-axis :$log_{10}$ $\frac{{[Z{n^{2 + }}]}}{{[C{u^{2 + }}]}}$, $Y$ -axis : $E_{cell}$
