1. The mass action law can be introduced by using a general chemical reaction equation in which reactants A and B react to give product C and D.
a A + b B --> c C + d D
where a, b, c, d are the coefficients for a balanced chemical equation.
The mass action law states that if the system is at equilibrium at a given temperature, then the following ratio is a constant.
------------- = Keq
The square brackets "[ ]" around the chemical species represent their concentrations. This is the ideal law of chemical equilibrium or law of mass action.
For the ionization of sulfuric acid the chemical equation is:
H2SO4 = 2 H+ + SO42-
What is the equilibrium constant expression?
The equilibrium constant is the products divided by reactants. We can model the equation above and we come up ...
The expert examines chemical equilibrium for constants, temperatures and concentrations.
