In chemistry, activation energy is what must be added to start a reaction.
The heat of the initial explosion would start a reaction at one end of the tube that would continue down its length.
Negotiating a terrible script, a gifted cast (Randy Quaid, Pam Grier, Jay Mohr) throws off a spark or two, but "they can't generate enough heat in this cold vacuum of a comedy to start a reaction" (Elvis Mitchell).
Sadly, though many of the actors throw off a spark or two when they first appear, they can't generate enough heat in this cold vacuum of a comedy to start a reaction.
The photons began breaking apart some of the methane molecules--essentially starting a reaction stopwatch.
This is possible because a small number of isotopes will capture neutrons produced in a reactor, starting a reaction that leads to a new, heavy fissile isotope.
You're already paying for a Netflix subscription, so it would be the same if you would play a video on Netflix.com and start a reaction video in another browser window.
"It reacts with this bio-catalyst, and that starts a reaction to separate carbon and the oxygen in that gas stream, and then goes through a fermentation process to further derive the material," says Mr Campbell.
We proposed the hypothesis that this reaction can be possible if we start a reaction using single stranded DNA as a template.
The first case happens if there are too few particles to start a reaction, e.g. when there are reactions in the network where at least one reactant species M has a stoichiometric coefficient l M > 1.
