1. Put the following line in the preamble
\newcounter{reaction}
\numberwithin{reaction}{chapter}
\newcommand{\reaction}{\addtocounter{reaction}{1}\tag{R. \thereaction}}
2. Select "Use ams math" in the document dialog (in "extra" tab in 1.1.6).
3. At each reaction, write \reaction at the end (inside the math inset).
Note that when you reference a reaction, you will get 'R. 2.1'.
