Is licl endothermic
WitrynaΔHsolution, LiCl = (852 kJ / mole) + [ (-519 kJ / mole) + (-381 kJ / mole)] = -48 kJ / mole < 0, so this reaction should be exothermic and it is as predicted. For NaCl, ΔHsolution, NaCl = (787 kJ... Witryna1 sie 2024 · So in short it's the opposite of #2: dissolving the first couple of molecules of $\ce {LiCl}$ is exothermic, but then if you dissolve more it become endothermic. The heat of dissolution to form an infinitely dilute solution is not the same as the heat associated with formation of a saturated solution.

So in short it's the opposite of #2: dissolving the first couple of molecules of LiCl is … WitrynaIn Sam’s case, when ammonium nitrate was dissolved in water, the system absorbed heat from the surrounding, the flask, and thus the flask felt cold.This is an example of …
Witryna1. Is the heat of solution of LiCl exothermic or endothermic? Explain your answer. 2. Is the heat of solution of NH4CI exothermic or endothermic? Explain your answer. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: 1. Witryna30 maj 2014 · So one might ask why might this endothermic process still occur. The answer lies with entropy; the dissolution of sodium chloride is not enthalpically favorable (dissolution consumes energy - specifically - from the water) - yet the dissolution is entropically favorable.
WitrynaWhich of the following processes are endothermic? * the reaction associated with the heat of formation of CaS. -------------FALSE * the formation of F2 from its elements in their standard states. * the reaction associated with the ionization energy of potassium. * the reaction associated with the lattice energy of LiCl. Witryna30 sty 2024 · This enthalpy of solution ( ΔHsolution) can either be positive (endothermic) or negative (exothermic). When understanding the enthalpy of solution, it is easiest to …
