Question

2. A 1.5 V alkaline battery is constructed based on a chemical process that involves the transfer of 2 electrons from anode to cathode per reaction. What is the change in free energy? 3. What is the most important use for a standard hydrogen electrode? 4. Suppose a NiMH battery is rated as 1.20 V and 1.50 A hr. Assuming one mole of electrons is transferred per mole of reaction, approximately how many grams of Nio(OH) (91.7 g/mol) are required to make this battery? How much electrical energy can this battery provide? MH + NiO(OH) M + Ni(OH);
