＋*General Q1
Can we use MALT under the LAN environment?
*General A1
No. MALT uses a USB dongle for the copy protection. You may install MALT on multiple PCs, but MALT works on only one PC with the dongle inserted at the time.
＋*General Q2
How does MALT offer its manuals?
*General A2
You can see the all the help,
MALT Omega、
MALT Basic,
CHD、
gem, in this site. And they are installed on a PC as well. There is a help button (or F1 key) in every operation form in each program, and it shows on demand, appropriate
help page.
There are no paper-printed manuals.
＋*General Q3
Can MALT/CHD draw Pourbaix diagrams?
*General A3
Although CHD was originally developed to construct high-temperature chemical potential diagrams, the algorithm for constructing generalized chemical potential diagrams can be applied to draw Pourbaix diagrams.
Since only the Omega version contains the thermodynamic data for aqueous species, the Omega version is actually needed.

What is GEF?
*Technical A1
GEF stands for Gibbs Energy Function. This function is the same as the free energy function used in the JANAF Thermochemical Tables. In MALT, this function is called the Gibbs energy function because the free energy was renamed the Gibbs energy (or Helmholtz energy).
Definition:
Here, T0 is the reference temperature, set to 0 K or 298.15 K. In the MALT database, 298.15 K is adopted.
How to use:
As the above equation indicates, this function is frequently used when the standard enthalpy change for a reaction at 298.15 K is derived from the high-temperature value of the Gibbs energy change for the reaction. Because the absolute entropy value at 298.15 K is used in the derivation of the Gibbs energy function, this procedure is called the third law method. Mainly, this treatment is used when the thermodynamic functions are derived from the vapor pressure measurements.
Since this function is not used in regular thermodynamic analyses, its details are not described in MALT's help.
