(chemistry only) Interpret data for relative reactivity of different metals in cells.

In the subtopic Cells and batteries, this learning objective focuses on (chemistry only) Interpret data for relative reactivity of different metals in cells. It belongs to Chemical cells and fuel cells (chemistry only) in AQA GCSE Chemistry 8462 Unit 4.5 Energy changes, so the explanation must stay inside energy-transfer, reaction-profile, cell, fuel-cell, exothermic, endothermic, activation-energy or bond-energy context as appropriate. Approved keywords to use include chemistry only, cell, metals, reactivity. Electrochemical reaction. means a chemical reaction that involves the transfer of electrons, producing electricity Avoid the mistake of students often confuse the reactivity of metals, thinking that all metals react similarly in cells regardless of their position in the reactivity series; instead, to fix this, students should study the reactivity series and understand that more reactive metals will displace less reactive metals in reactions, affecting the voltage produced in cells For exam answers, familiarize yourself with the reactivity series of metals and how it affects cell voltage
