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

Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration

Report: Calculating the Spring Constant and Verifying that Energy is Conserved Within a System Abstract: An experiment was conducted to determine the spring constant of a spring in the cart by measuring the force required to compress a spring as well as the distance the spring compressed relative to the equilibrium position. A cart was placed onto a slanted track and speed and force censors were used to record appropriate data. The spring constant was determined by substituting

molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem. The four factors or variables for gas are: pressure (P)‚ volume (V)‚ number of mole of gas (n)‚ and temperature (T)‚ and the constant in the equation is R‚ known as the gas constant. The Ideal Gas law equation which is pV=nRT is obtained by combining the

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
