<p>For question 8(d)(ii), why is the reduction half reaction not Na+ + e- ->Na(s)? Could someone quickly explain please? Thanks.</p>

<p>Also, if I've been consistently gettin 80% correct on the FRQs, how much would you anticipate that I need to get right on the MCs for a 5?</p>

You want the reduction potential, therefore you want I</p>
