Relationship between Heat and Electron Volts in a reaction

Click For Summary
SUMMARY

The discussion centers on the relationship between heat released during a chemical reaction and the current generated when reactants are configured in a battery setup. Specifically, it examines the reaction between zinc and copper sulfate, which produces heat and charged particles. The inquiry seeks to establish a formula or physical relationship that correlates the heat released with the current generated in a galvanic cell configuration. The participants emphasize the need to understand whether the reactions proceed equivalently in both scenarios.

PREREQUISITES

Hi,
Im trying to understand the relationship between heat released in an energetically favourable chemical reaction and the released charged particles when the reactants are connected in a battery set up.

If you mix Zinc and copper sulphate you get heat and the product. Connect the copper and zinc in solution them with a salt bridge you get a flow of current and the product.

Is there a physical relationship/formula between the amount of heat released to predict the amount of current that would have been generated had you connected the reactants in a battery style set up.

Ask yourself if the reactions proceed to the same extent in both cases.
