Is it a Barron's error?

<p>the reaction Fe --->Fe(2+) + 2e- (+0.44 volt) would occur spintaneously with which of the following?</p>

<p>I. Pb --> Pb (2+) + 2e- (+0.13 V)
II. Cu --> Cu(2+) + 2e- (-0.34 V)
III. 2Ag(+) + 2e- --> 2 Ag (+0.80 V)</p>

<p>This answer given by Barron is I II and III </p>

<p>it simply adds the three Standard Reduction Potentials to +0.44V and gets three positive results.</p>

<p>But I think I and II don't make sense because electrons don't conserve!! </p>

<p>Am I right?</p>
