For modest temperature excursions away from 25 C, the change in E for a half-reaction can be written in the form

where E°(T) is the standard reduction potential at temperature T (°C), and ˆ†T is (T - 25). For the reaction ,Al3+ + 3e- ‡Œ Al(s) dE° /dT = 0.533 mV/K near 25°C. Find E for this half reaction at 50°C
