question: Mike is watching how particles of reactants function, and sees that they are crowded very close. Considering that the concentration of them is very high, the chance of them colliding together is
choices.text: high low
choices.label: A B
para: At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react.
