2. The standard reduction potential for the Zn2+Ι Zn couple is -0.67 volts. What would the reduction potential be if the Zn2+ solution has a concentration of 0.01 M and is at a temperature of 16.8 °C?
Enter your answer in volts, and use three significant figures. Include a "-" sign if your potential is negative, but do not use a "+" sign if it was positive.

Zn2+(aq) + 2e-
Zn(s)
E = E° - RT/nF × ln Q
= -0.67 - 8.314×(273.15+16.8)/(2×96485) × ln(1/0.01)
= -0.67 -0.05753
= -0.72753 V
E (reduction potential ) = - 0.728V (Answer)
