← ScienceWhich mechanism causes endothermic behavior during solid dissolution?
A)Latent heat absorption exceeds solvation✓
B)Kinetic energy reduction dominates mixing
C)Entropy decreases causing self-assembly
D)Solute diffusion limits heat transfer
💡 Explanation
Endothermic dissolution happens because the phase change latent heat absorption overcomes intermolecular solvation energies; therefore, temperature decreases as solid dissolves, rather than increasing due to increased solubility at higher temperatures.
