reaction where the concentration of all the reactants and all the products remain constant over time. Equilibrium as used in chemical systems means that all the chemical forces in a reaction are in balance and that all physical properties of the system (color‚ density and concentration) of all chemicals species involved remains constant. The equilibrium state can be characterized by quantitatively defining its equilibrium constant‚ Keq. In this experiment the Keq for the reaction between iron (lll) ions

Lab: Electrostatic Coulomb Constant Rylee Rose Date: 1/28/13 Abstract: This experiment was done to study electrostatic and Coulomb’s law. Objective: The objective was to demonstrate the veracity of Coulomb’s Law. This was done by observing different equilibrium conditions of two pith balls that were equally charged. They were then constructed into a pendulum using strings. Calculations were done to determine the charge on pith balls‚ calculate the mass of the pith balls and to calculate
