What is the fastest chemical reaction?

Ultra-fast Chemical Reaction that Turns Graphene into Semiconductors. German and US scientists recently reported an unusual feat: they observed the world’s fastest chemical reaction, during which hydrogen atoms bind onto and then leave a sheet of graphene, all within ten quadrillionths (10^-14) of a second.

Is 200ms a good reaction time?

The hard limit for human reaction speed is around 200ms in an empty situation. If you’re looking for a specific thing, you are very well-conditioned, but it could happen at any time, so you’re going to react to it around 200ms or slower on the average. Now, 200ms is superhumanly fast.

What is the fastest reflex in the human body?

There are many various reflexes that can occur simultaneously during a startle response. The fastest reflex recorded in humans happens within the masseter muscle or jaw muscle. The reflex was measured by electromyography which records the electrical activity during movement of the muscles.

What is the fastest possible human reaction time?
