Hi, I'm having trouble with this simple reaction (1):
$$A + A → I$$
with ##R = kC^2_A##
I'm assuming it takes place in a Batch reactor so the mass balance should yield:
$$\frac {dC_A} {dt} = -2R = -2kC^2_A$$
But, as I recall (I should be wrong though), stoichiometry in thermodynamics and kinetics is just "math": it does not have any "physical" meaning (unlike in chemistry), but it only serves to assure mass is conserved during the reaction.
So I can re-write reaction (1) like:
$$ A → \frac 1 2 I$$
But now:
$$\frac {dC_A} {dt} = -R = -kC^2_A$$
What am I missing ?
