Based on the sign of E°cell, classify these reactions as spontaneous or nonspontaneous as written. Assume standard conditions.
We´re asked to classify these reactions based on the sign of E°cell assuming standard conditions.
Remember that E°cell > 0 is spontaneous, while E°cell < 0 is nonspontaneous.
To determine that, we require to calculate E°cell using the following equation:
When a balanced reaction is given, identify the anode and the cathode half-reactions by determining the changes in oxidation states of each species based on the given reaction:
Cathodereductionoxidation number decreases
Anodeoxidationoxidation number increases
