Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine

TOPIC - 2 DEMAND‚ SUPPLY AND MARKET EQUILIBRIUM The term ‘price’ has a great relevance in economics. In ordinary usage‚ price is the quantity of payment or compensation given by one party to another in return for goods and services. It is generally expressed in terms of units of some form of currency. But how does a product sell for a certain price‚ what constitutes the price of a product and how is the price determined is the bigger question. In economics‚ for a competitive market

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

Chemical Equilibrium Lab Report Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions. Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change. This lab consists of two

Individual Assignment #1 1. Briefly point out the faulty reasoning in each of the following situations: a. You win a free‚ nontransferable ticket to a Sheryl Crow concert. Since the ticket is free and it will therefore cost you nothing to go‚ you decide to go to the concert. b. You paid nonrefundable tuition of $3‚000 to take a 15-week course. Therefore‚ the opportunity cost of attending class each week is $3‚000 divided by 15‚ or $200. c. You have purchased

Spectrophotometric Determination of an Equilibrium Constant. Abstract: The report presents determination of equilibrium constant for the formation of a complex ion FeSCN2+. This was accomplished using a colorimeter to measure absorbance of some known concentration solutions in order to generate the calibration curve. The equation of the graph was used to compute the equilibrium concentrations of the reactants and products‚ needed to calculate the equilibrium constant for the reaction.

Demand‚ Supply and Market Equilibrium Every market has a demand side and a supply side and where these two forces are in balance it is said that the markets are at equilibrium. The Demand Schedule: The Demand side can be represented by law of downward sloping demand curve. When the price of commodity is raised (ad other things held constant)‚ buyers tend to buy less of the commodity. Similarly when the price is lowered‚ other things being constant‚ quantity demanded increases. The above

Torques equilibrium‚ and center of gravity Introduction Torque is a quantitative measure of the tendency of a force to cause or change the rotational motion of a rigid body. A torque is the result of force acting at a distance from an axis of rotation. An essential thing to keep in mind is that the magnitude of the torque is equal to the product of the forces perpendicular distance and magnitude. Theory The magnitude of the torque (t) is found from the product of the force F and

Market Equilibrium of Crude Oil Gina Brazelton Economics 561 April 17‚ 2012 Dr. Jill Trask Market Equilibrium of Crude Oil Market equilibrium occurs when there is no shortage or surplus of a product‚ therefore‚ buyers and sellers get what they want. When there is a change in either the supply or demand this will eventually adjust to a new equilibrium of price and quantity. Right now‚ industries are not only faced with ever-changing periods of consumer demand but their own production inventory
