Cyclopropane, c3h6, is converted to its isomer propylene, ch2=chch3, when heated. the rate law is first order in cyclopropane, and the rate constant is 6.0 × 10−4/s at 500°c. if the initial concentration of cy- clopropane is 0.0226 mol/l, what is the concentration after 525 s?

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
