kinetic rate unit measurement

(1/1)

Selene Eliana Patani:
Hi everybody! My question is very simple: which is the default unit of measurement of the kinetic rate in phreeqc? mol/m3/s or mol/L/s? thank you very much in advance!!

dlparkhurst:
You must calculate moles for the amount of time given by the internal variable TIME.

If you have have an expression for rate, r, in mol/L/s then you would use the following Basic statements (arbitrarily 100 and 110):

100 moles = r * SOLN_VOL * TIME
110 SAVE moles
