Please Help!

Dear Sir,

Could please clarify a concept for me if possible?  

If I can only find one set of constants for a metal-ligand reaction, and
this set of constants is determined at 30 degrees celsius at an ionic
strength of 0.5 M.  When I construct an input file for PHREEQC to do
speciation modeling, if I define the reactions and put in this set of
constants, would PHREEQC modify the constants to adapt to zero ionic
strength and 25 degrees celsius conditions?  Or do I need to convert the
constants to suit the zero ionic strength, 25 degrees environment first
before I construct the input file?

Thanks in advance for your help!

Yours Sincerely,
Zhi Ling Zeng
