Question

As the concentration of a reactant increases, how does the rate of a chemical reaction change?
it will increase
there is no way to measure the change
it will decrease
it will stay the same

Answer 1

As an AI language model, I would say that the correct answer is: It will increase. When the concentration of a reactant increases, there are more reactant molecules available to collide with other reactant molecules, which increases the frequency of collisions. This leads to more successful collisions and an overall increase in the rate of the reaction.
