Answer:
The question isn't worded properly, but if 1 or 2 are DECREASED, the frequency of collisions of specified molecules will decrease.
Explanation:
Catalysts only facilitate reaction once molecules collide. Increased temperature makes molecules move more, and thus collide more. For concentration, if there are more molecules in the same amount of room/liquid, there will be more collisions because there are more of the molecules to collide.
Answer:
76.9L
Explanation:
Based on the graph, whenever the temperature increases by 100K, the volume increases by 10L, so do 769/10
They rarely occur at molecular levels is incorrect, actually they always occur at molecular levels
Maybe because the difference in weight
