Free Radicals at STP
« on: November 27, 2018, 01:55:14 AM »
Why can’t free radicals participate in redox reactions ar STP? For example the reaction between sodium and chlorine is always written as 2Na(s) + Cl2(g) ——> 2NaCl(s) instead of as Na(s) + Cl(g) ——> NaCl(s)

At STP they recombine way too fast to exist in significant amounts and have any serious impact on this kind of reaction.

A reaction written that way only describes the reactants and products, not the intermediates.

Reaction steps may involve free radicals, in extremely small amount and very short-lived, as they take much more energy to produce than is available from the temperature as a mean.
