Unit 4 Section 19: 3.1.10 Equilibrium constant Kp for homogeneous systems

3.1.10 Equilibrium constant Kp for homogeneous systems
The further study of equilibria considers how the mathematical expression for the equilibrium constant Kp enables us to calculate how an equilibrium yield will be influenced by the partial pressures of reactants and products. This has important consequences for many industrial processes.
