Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial

Physics lab:9 Equilibrium of parallel force 11/09/2012 By: Camilo Salazar Jillian Ellis Purpose: To understand the conditions need for a rigid body to be in equilibrium when there are forces acting on the body from different sides. Theory: When force is applied on a rigid body for example a ruler it can either be in equilibrium or it can be unbalance. When the force is unbalance what would happen is this motion the body can be either translational or rotational. “A body in translational

Temperature and Equilibrium Virtual Lab Change is influenced by many different factors in many different situations. If you imagine the 400‚000 gallons of water in a stream at the top of a hill‚ you can picture that they will flow down the hill in order to reach equilibrium. But what if the temperature outside is -40 degrees Fahrenheit? How might this change the movement of the water molecules down the hill? This virtual lab will allow you to explore how temperature changes affect two linked

CH 127 – Chem 2 Lab Determination of an Equilibrium constant Goals The purpose of this experiment is to determine the equilibrium constant for the reaction Fe3+(aq) + HSCN(aq) –>FeSCN2+(aq) + H+(aq). The equilibrium constant expression Kc for Reaction is kc=FeSCN2+[H+]Fe3++[HSCN] Procedure *Preparation of the Beer’s law plot Prepare five solutions of FeSCN2+(aq) of known concentrations between 1x10-5M and 1x10-4M by diluting various volumes of 4.62x10-4 HSCN.

The market is a place where buyers and sellers come together to make a business transaction. This market can be anything from the New York Stock Exchange to a roadside farmer’s stand‚ all of these markets are made up of both supply and demand schedules. Both supply and demand are affected by determinants that either shift the lines right or left or cause movement along the line. The point where the two lines intersect is the Equilibrium‚ the equilibrium point is simply it is where quantity demanded

Supply and Demand Factors Understanding supply and demand is the underlying foundation of all economics. The term demand is used to indicate consumers’ willingness to buy while supply indicates willingness to sell. The relationship between demand and price is reflected by quantity demanded‚ meaning that at a certain price with everything else held constant‚ this is the amount people are willing to buy. The same applies for supply for quantity supplied‚ at a given price with all else constant this
