Title: kinetic rate unit measurement
Post by: Selene Eliana Patani on January 08, 2018, 12:02:58 PM
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!!

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
