The rate at which a solute dissolves in a solvent depends on the kinetic energy of the solution, the time 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 change may be more pronounced depending on the thermodynamic parameters of the reaction. as the kinetic energy, time of contact, and surface area of contact between the solute and the solvent particles increase, the rate at which the solute undergoes dissolution in a solvent increases. similarly, as the kinetic energy, time of contact, and surface area of contact between the solute and the solvent particles decrease, the rate at which the solute undergoes dissolution in a solvent decreases. the dissolution process can be altered by varying these parameters, such as by increasing or decreasing the temperature or by reducing the particle size of the solute. consider the preparation of a nacl salt solution using coarse crystals of nacl in an unstirred container at room temperature. classify the following conditions based on the change in the rate of dissolution of nacl in water compared to the initial preparation if the dissolution process is endothermic.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
