What could happen if a student placed a hot, clear solution that contained a solute to be recrystallized directly in an ice bath, prior to allowing the solution to cool to room temperature

At room temperature what happens to the average kinetic energy of the molecules of a solid, liquid, and a gas

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

The diagram below shows the movement of particles. what does this piece of evidence best support? the collision theory the maxwell-boltzmann distribution the effect of pressure on reaction rates the effect of temperature on reaction rates
