#Delta"G"=Delta"H"^@-"T"Delta"S"#

Explanation:

In order to calculate the free energy for a reaction, the above equation should be used. Thus, the temperature of the experiment, in Kelvin, must be known.

Also, #Delta"S"# is given in #"J"# #"K"^-1# #"mol"^-1#, thus it must be converted into #"kJ"# #"K"^-1# #"mol"^-1#, otherwise the #Delta"G"# value will be incorrect.
