Answer:
when concentration increases, particles colide more often
The statement "When concentration increases, particles collide more often" is correct.
What is concentration?
A constituent's abundance divided by the entire volume of a combination is known as concentration. Mass concentration, molar concentration, number concentration, and volume concentration are all examples of mathematical descriptions.
There are much more reactant particles travelling together as the concentration of reacting species increases. Because there would be more collisions, the reaction rate will be faster. The rate of a reaction increases as the concentration of reactants increases.
