question: Ian sees an object with many colliding particles, and he compares it to another object with few colliding particles. Which is true about the objects?
choices.text: the object with many colliding particles has a lower concentration of particles the object with many colliding particles has a higher concentration of particles
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: likely to collide and react
para_anno.cause_dir_str: higher
para_anno.effect_dir_str: more
para_anno.cause_dir_sign: MORE
para_anno.effect_dir_sign: MORE
para_anno.cause_prop: concentrations of particles
question_anno.more_effect_dir: higher concentration
question_anno.less_effect_dir: lower concentration
question_anno.less_cause_prop: particles
question_anno.more_effect_prop: particles
question_anno.less_effect_prop: particles
question_anno.less_cause_dir: particles
