APFIVE Temperature Effect on Cell Potential
The standard cell potential, E°cell, for a redox reaction is +0.25 V at 25°C. When the temperature is increased to 60°C, the E°cell decreases to +0.20 V. What can be concluded about the standard entropy change, ΔS°, for this reaction?
A
ΔS° cannot be determined from this information
B
ΔS° is negative
C
ΔS° equals zero
D
ΔS° is positive
