A reaction occurs between two gases when they are mixed. Which is the most likely effect on reaction rate if the gases are mixed at the same temperature but at higher pressure? 1. Reaction rate increases because the molecules collide more often.
2. Reaction rate increases because the molecules collide with more force.
3. Reaction rate decreases because the molecules have less room to move.
4. Reaction rate stays the same because the molecules move at the same speed.

Iknow the answer is a but i don't know why

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
