of this lab is to experimentally determine the equilibrium constant‚ Kc ‚ for the following chemical reaction: Fe3+ (aq) + SCN-(aq) ↔FeSCN2+(aq) Background Information: A system is at equilibrium when the rate of the forward reaction is the same as the rate of the reverse reaction. There is no change in concentration for the reactants or products at chemical equilibrium. When the system is disturbed there is a shift to reestablish equilibrium explained by Le Chatelier’s Principle. It states

Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant‚ Ksp‚ of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated

Concentration The Problem In many colleges over 8% of the students report problems concentrating on their studies. Most of these students blame outside distractions for their problems. Many research studies manipulating noise levels and distractions have found that such disturbances may increase‚ decrease‚ or not even affect concentration. These researchers have therefore concluded that distracters don’t cause concentration problems directly. It is the way the distracters are interpreted

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

Chemical Equilibrium ------------------------------------------------- ------------------------------------------------- RESULTS AND DISCUSSION A. Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

Equilibrium Kurt Wimmer’s film Equilibrium (2002) is set in color. It tells a story about how suppressing emotions eliminates war‚ and any books‚ art‚ or music is forbidden. Those who are caught being a sense offender has committed a crime punishable by death. The film demonstrates the true source of man’s inhumanity to man. The internal struggle within the characters throughout the film such as with the main character Cleric John Preston (Christian Bale)‚ contributes to the theme of the Truth of

Equilibrium Paper By: Brandon Walker ECO/561 July 14‚ 2014 Instructor: Mark Erenburg This paper was written to describe a real world experience in a free market were change occurred in supply or demand as a result of world events that led to the need for a move between two equilibrium states. I will also explain the process of how that movement occurred using behavior of consumers and suppliers while using graphs as indicated. Real Word Experience According to a United

Nash Equilibrium and Dominant Strategies Nash Equilibrium is a term used in game theory to describe an equilibrium where each player’s strategy is optimal given the strategies of all other players. A Nash Equilibrium exists when there is no unilateral profitable deviation from any of the players involved. In other words‚ no player in the game would take a different action as long as every other player remains the same. Nash Equilibria are self-enforcing; when players are at a Nash Equilibrium they
