D) The average kinetic energy of the molecules that make up the solution also increases with increasing temperature. This increase in kinetic energy allows the solvent molecules to more effectively break apart the solute molecules that are held together by inter-molecular attractions.
<h3>Explanation;</h3>
<em><u>Solubility refers to the amount of a substance that can dissolve in a solution at a given temperature.</u></em>
<em><u>Solubility increases with increase in temperature, this is because higher temperature of the solvents increases the kinetic energy of the particles in the solvent, thus they will vibrate more faster, which makes them to break apart the molecules of the solute that are held by inter-molecular forces more effectively.</u></em>
The slope of the graph is what you need. That tells you the speed not the velocity. In order to find the velocity you would also need to know the direction of the motion.
