Question

Calculate E°cell (in V) and indicate whether the overall reaction shown is spontaneous or nonspontaneous under standard conditions:

	A.	E°cell = –1.63 V, nonspontaneous
	B.	E°cell = 3.11 V, spontaneous
	C.	E°cell = 1.63 V, nonspontaneous
	D.	E°cell = 1.63 V, spontaneous
	E.	E°cell = –3.11 V, nonspontaneous

2 Cr3+(aq) + 3 Mg(s) → 2 Cr(s) + 3 Mg2+(aq)
