Question: What is the effect of increasing the temperature on the cell potential of an electrochemical cell?

Options:

Correct Answer: Depends on the reaction

Solution:

The effect of temperature on cell potential depends on the reaction\'s enthalpy change (ΔH).

What is the effect of increasing the temperature on the cell potential of an electrochemical cell?

What is the effect of increasing the temperature on the cell potential of an electrochemical cell?

Step 1: Understand that an electrochemical cell generates electricity through chemical reactions.
Step 2: Know that the cell potential is the voltage produced by the cell.
Step 3: Recognize that temperature can affect how fast and how much the reactions occur.
Step 4: Learn about enthalpy change (ΔH), which tells us if a reaction absorbs or releases heat.
Step 5: If ΔH is positive (endothermic), increasing temperature usually decreases cell potential.
Step 6: If ΔH is negative (exothermic), increasing temperature usually increases cell potential.
Step 7: Conclude that the effect of temperature on cell potential depends on whether the reaction is endothermic or exothermic.
