The free energy change for the following reaction at 25 °C, when [Hg2+] = 1.19 M and [Zn²+] = 3.01x10-³ M, is -327 kJ: Hg2+(1.19 M) + Zn(s)→→→ Hg(1) + Zn²+(3.01×10-³ M) AG = -327 kJ What is the cell potential for the reaction as written under these conditions? Answer: V Would this reaction be spontaneous in the forward or the reverse direction?

The free energy change for the following reaction at 25 °C, when [Hg2+] = 1.19 M and [Zn²+] =
3.01x10-3 M, is -327 kJ:
Hg2+(1.19 M) + Zn(s)→→→→→ Hg(1) + Zn²+(3.01×10-³ M) AG = -327 kJ
What is the cell potential for the reaction as written under these conditions?
Answer:
V
Would this reaction be spontaneous in the forward or the reverse direction?
