question: Mike is watching how particles of reactants function, and sees that they are very far apart. Considering that the concentration of them is very low, 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.
para_anno.effect_prop: chance of collision
para_anno.cause_dir_str: higher
para_anno.effect_dir_str: more
para_anno.cause_dir_sign: MORE

para_anno.cause_prop: concentrations
question_anno.more_effect_dir: high
question_anno.less_effect_dir: low
question_anno.less_cause_prop: particles
question_anno.more_effect_prop: chance of colliding
question_anno.less_effect_prop: chance of colliding
