Formula used
E = E° − (RT/nF)·ln Q
Every result substitutes your values into this relation step by step above.
Assumptions
- Q uses the same species/exponent conventions as K; pure solids/liquids omitted.
- The familiar 0.0592/n coefficient applies ONLY at 25 °C — other temperatures computed exactly from RT/nF.
