Three students are mixing the same type of solute in 500 ml of water. jessica is heating her solution, larry left his on the counter at room temperature, and hunter is heating his solution while stirring it. which ranks who would fully dissolve the solute, from first to last? a. larry → jessica → hunter b. hunter → jessica → larry c. jessica → hunter → larry d. hunter → larry → jessica

Option (a) is the correct answer.

Explanation:

According to collision theory, more is the number of collisions between the particles of reactants or a substance then more will be the rate of reaction.

Therefore, when we heat the solution then it will take time to heat up and thus, molecules will gain kinetic energy after a few minutes. As a result, collisions will start to occur and eventually rate of reaction will increase.

Whereas when we stir the solution while heating then immediately a disturbance is caused due to which atoms start to move and thus they gain kinetic energy. Therefore, rate of reaction will increase much faster due to stirring while heating.

On the other hand, when solute is dissolved into the solution and if no disturbance is caused then the reaction will be slow in nature as molecules are not colliding rapidly.

Hence, we can conclude that ranks who would fully dissolve the solute, from first to last are as follows.

                        Larry → Jessica → Hunter

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
