Question

Zinc is stirred into copper sulfate solution.
Initial temp. of copper sulfate= 20 degree C
Final temp. of solution= 45 degree C

Is this exothermic or a endothermic reaction?Explain.

Answer 1

Heya

Initial temperature of the solution = 20°C

Final temperature of the solution = 45°C

From the given data, we can see that there is an increase in the temperature.

This temperature increases due to the release of energy.

So, it is an exothermic reaction.

Exothermic reaction :- These are those reactions in which there is a release of heat and it basically increases temperature of the reaction.

Hope this helps.
