Question

Reaction between Lead Nitrate and potassium iodide is exothermic or endothermic ??​

Answer 1

Answer:

here's your answer

This is endothermic, and so increasing the temperature of the solution will promote the dissociation of lead(II) iodide.

Answer 2

Answer: The reaction between Lead Nitrate and potassium iodide is endothermic.

Explaination:

Pb(NO₃)₂ + 2 KI → PbI₂ + 2 KNO₃

• In this reaction, the bonds between the lead ion (Pb₂⁺) and the nitrate ions (NO₃⁻) in lead nitrate and the bonds between the potassium ion (K⁺) and the iodide ion (I⁻) in potassium iodide are broken in order to form new bonds between the lead and iodine ions and between the potassium and nitrate ions.

• Breaking bonds requires energy, which means that the reaction requires an input of energy in order to proceed. Therefore, this reaction is endothermic.

The reaction between lead nitrate and potassium iodide is an example of a double displacement reaction.

An exothermic reaction is one that releases heat energy, while an endothermic reaction is one that absorbs heat energy.
