The equilibrium constant is related to the Gibb's free energy for the reaction through where the D G A,B,C,D are free energy changes relative to the standard states. As usual, the D G RXN is defined by that of the products minus reactants. The greater the heat evolved or used in the reaction, the greater the effect of temperature change on the equilibrium. Water acts as a Bronsted base, accepting the proton from the acid. The oxidant oxidizes a reduced species and a reductant reduces an oxidized species.
Electrons are either effectively or actually transfered reductant to the oxidant.
In the above reaction, o 1 moles of Ox 1 are reduced to r 2 moles of Red 2 while r 1 moles of Red 1 are oxidized to o 2 moles of Ox 2 . Ox 1 is an oxidant since it oxidizes Red 1 to Ox 2 . Often equilibrium involves a number of intermediate steps. This page was created by Professor Stephen Bialkowski , Utah State University .
