What is the effect of increasing temperature on the cell potential?
Correct Answer: Cell potential increases with temperature for endothermic reactions and decreases for exothermic reactions.
- Step 1: Understand what cell potential is. It is the measure of the voltage produced by a chemical reaction in a cell.
- Step 2: Know that temperature can affect chemical reactions. Higher temperatures can increase the energy of the molecules involved.
- Step 3: Recognize that the effect of temperature on cell potential depends on the specific reaction taking place.
- Step 4: Learn about enthalpy change. This is the heat change during a reaction at constant pressure.
- Step 5: If a reaction absorbs heat (endothermic), increasing temperature usually increases cell potential.
- Step 6: If a reaction releases heat (exothermic), increasing temperature usually decreases cell potential.
- Step 7: Conclude that the overall effect of temperature on cell potential varies based on whether the reaction is endothermic or exothermic.
