Question

A solid reactant is placed into a beaker of a warm water. The liquid vigorously bubbles as the solid dissolves into the solution. What will most likely happen if the temperature of the liquid is slightly reduced?
More bubbles will be produced because the solution is becoming more concentrated.
Fewer bubbles will be produced because of fewer collisions of reactant molecules.
The solid will get smaller at a faster rate because of more collisions of reactant molecules.
The solid will get larger at a slower rate because precipitate is coming out of the solution.

Answer 1

Answer: Fewer bubbles will be produced because of fewer collisions of reactant molecules.
