From 10cead4950e2ff68aecc95f8b064fd018e533932 Mon Sep 17 00:00:00 2001 From: "Bryan W. Weber" Date: Wed, 18 Dec 2013 17:46:32 +0000 Subject: [PATCH] [Doc] Fix typos and formatting in reactions.rst Add +M to the three-body reaction's reactants. Update formatting of species names in the following paragraph. Update formatting of 'units' arguments.
