of product composition
Synonym: equilibrium control
https://doi.org/10.1351/goldbook.T06316
The term characterizes conditions that lead to reaction products in a proportion governed by the
equilibrium constant
for their interconversion and/or for the interconversion of reaction
intermediates
formed in or after the
rate-limiting step
. (Some workers prefer to describe this phenomenon as 'equilibrium control'.)
