Experimental evidence shows that there is a link between the concentrations of reactants and products in an equilibrium mixture at constant temperature. In this topic we explore that link to reveal the Equilibrium Law.
After working through this topic you will be able to:
- devise an expression for the equilibrium constant, Kc, for homogeneous and heterogeneous reactions;
- interpret Kc qualitatively, decide on units for Kc and calculate values of Kc from experimental data;
- understand some of the difficulties that students have with the Equilibrium Law and the strategies that are available to help them.
