Question

$Pt(s) | H_{2_{(g)}} (1 bar) | H^{+}_{(aq)}(1M) || M^{3+}_{(aq)}, M^{+}_{(aq)} | Pt(s)$
The E_cell for the given cell is 0.1115 V at 298 K when $\frac{[M^+(aq)}{[M^{3+}(aq)]}=10^{a}$
The value of a is _________
Given: $E^{\theta}_{M^{3+}/M^+}=0.2\;V$
$\frac{2.303RT}{F}=0.059V$

Answer 1

Correct Answer: 3

The value of a is 3.
