HSC does all the above instantly - you simply type the reaction equation in the input field and HSC gives you the heat of the reactions, the equilibrium constant at any temperature and the amount of species. HSC even checks the elemental balance and gives potentials vs. the standard hydrogen electrode for electrochemical reactions.
The calculated heat of reaction is the amount of heat that will be absorbed or released in the reaction. The equilibrium constant predicts the direction of the reaction. User input may be in the form of simple formulas or chemical reactions:
Na2SO4
Mg = Mg(g)
2Al + 3/2O2(g) = Al2O3
H2O = 1/2O2(g) + 2H(+a) + 2e-
Ag = Ag(+a) + e-
3NO2(-a) + H(+a) = 2NO(g) + H20 + NO3(-a)
2Al(+3a) + 3S(-2a) + 6H2O = 2Al(OH)3 + 3H2S(g)
