Question

rewrite this but as a 9th grader chemical reaction, reactants must collide with enough energy for a reaction to occur. If the concentration of the reactant approaches zero, the likelihood of reactant particles colliding decreases significantly, which means the reaction rate will slow down considerably

Answer 1

In a chemical reaction, the reactants need to bump into each other with enough energy for the reaction to happen. If the concentration of the reactants gets really low (like if there aren’t many particles around), the chances of these particles colliding become much less likely. This means the speed of the reaction will slow down a lot.
