Consider the following half-cell reactions, namely 

$$\text{H}^+(aq) + e^- \rightleftharpoons \frac{1}{2}\text{H}_2(g)$$ with $$E^\circ = 0.00$$ V, 

$$\text{V}^{3+}(aq) + e^- \rightleftharpoons \text{V}^{2+}(aq)$$ with $$E^\circ = -0.255$$ V, 

$$\text{VO}^{2+} + e^- + 2\text{H}^+ \rightleftharpoons \text{V}^{3+}(aq) + \text{H}_2\text{O}(l)$$ with $$E^\circ = +0.337$$ V, and

$$\frac{1}{2}\text{O}_2(g) + 2e^- + 2\text{H}^+ \rightleftharpoons \text{H}_2\text{O}(l)$$ with $$E^\circ = +1.23$$ V. 

Using the above equations, the correct statements are
