to main test pageIn general you can not see definitively from the
1/r(U) - plot when concentration controlling is necessary. Take for instance a
simple consecutive reaction! (see further link ! ).
The reason is that the 1/r(U)-plot 'represents only' the consumption of the
educt, you don't see any information on the product-formation / -distribution.
On the other hand: when you encounter some 'strange behaviour' (function not
steady or mounting close to the origin) in the 1/r(U) - plot - as described in
previous and/or following texts (see example) - , you can normally expect
the necessity for concentration controlling.
| In general you should put yourself the question: ' Is the product formation linked obviously to the conversion of the educt, yes or no ?' When 'no', you have to examine the reaction kinetics thoroughly. |
rem: don't additionally forget thermal effects,
catalytic reactions, multiphase reactions etc., where the matter gets more
complex!
