Chemical reactions take place so rapidly — often
within picoseconds, or a trillionth of a second — that chemists expect intermediate steps in the reaction to be too brief to observe.
Does this mean that if I place say 400 (or even an infinite number of) thermocouple devices at various positions
within his heating pan of water and take measurements to determine «heat» at say 3 time points a couple of
picoseconds apart, I will understand the trend regardless of the timing of my experiment (i.e. at what point after application of the heat source I took my first measurement) and regardless of the intensity of the heat source?
