A chemical reaction produces very stable molecules from highly reactive molecules. The products are two solids, while the reactants are a liquid and a gas. What type of thermodynamic process is this reaction? Why? Endothermic rxn that is increasing the entropy of the system. Thus, it is a Type 4 reaction O Endothermic rxn that is decreasing the entropy of the system. Thus, it is a Type 2 reaction Exothermic rxn that is increasing the entropy of the system. Thus,...

Hello, I need help solving the 3 parts of this question.
Part - Factors affecting the dissolution process The rate at which a solute dissolves in a solvent depends on the kinetic energy of the soluton, theme of contact and the surface area of contact between the solute and the solvent particles. Both endothermic and exothermic dissolution processes will respond similarly to each factor, however the charge may be more pronounced depending on the thermodynamic penters of the reaction. As...
