CONDITION OF EQUILIBRIUM IBAÑEZ‚ Jonen Lery L. OBJECTIVE A torque is an influence‚ which tends to change the rotational motion of an object. One way to quantify a torque is force applied times the lever arm. In this experiment we consider the systems in equilibrium and its applications and how the forces acting on the system affect torque. To serve as a guide there are objectives set in performing this experiment. First objective is by the second condition applied to the systems of equilibrium and the

SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT OF A REACTION UNIVERSITY OF THE PHILIPPINES‚ DILIMAN QUEZON CITY‚ PHILIPPINES August 2‚ 2013 ABSTRACT The objective of this experiment is to determine the equilibrium constant‚ denoted Keq‚ for the formation of [Fe(SCN)]2+ complex which is a product of the reaction between the ions Fe3+ and SCN-. In performing this experiment‚ solutions containing FeCl3 and KSCN‚ diluted in HCl‚ were measured for their absorbance using a UV-Vis

Experiment No. 2: Dynamic Equilibrium and Le Chatelier’s Principle December 1‚ 2011 Final Formal Results Le Chatelier’s Principle states that “when a stress is applied to a chemical system at equilibrium‚ the equilibrium shifts in a direction that reduces the effect of stress” (Gross‚ Abenojar‚ and Tan 23). Moreover‚ it helps us “predict the direction of the shift of the equilibrium” (Silberberg 745). Silberberg also stated that there are three kinds of disturbances - concentration‚

Market Equilibrium Process Economics/561 Monday‚ February 6‚ 2012 Professor Michael Shackelford Market Equilibrium Process According to "Business Week" (n.d.) “Market equilibrium is a situation in which the supply of an item is exactly equal to its demand. Since there is neither surplus nor shortage in the market‚ price tends to remain stable in this situation.” (Market Equilibrium). The market equilibration process is very important to manufactures and sellers in the marketplace

DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

Another objective is to explain how changes in temperature‚ pressure and concentration affect the equilibrium position of a reaction. Also‚ perform chemical equilibrium reactions and manipulate equilibrium positions through concentration and temperature and perform calculations to determine the equilibrium constant (K) and the reaction quotient (Q) of

Supply and demand is one of the most fundamental concepts of economics and it constitutes the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers while supply represents how much the market can offer. The quantity supplied refers to the amount of a certain product manufacturers are willing to supply given a set price. (Investopedia.com - Your Source For Investing Education‚ 2011). The law of supply and demand defines the effect that the
