The Equilibrium Constant of an Ester Hydrolysis Reaction CHM 152LL Section 33263 March 28‚ 2014 John Weide Abstract: The purpose if this experiment is to determine the equilibrium constant of an unknown alcohol. In this experiment unknown alcohol number three and unknown ester number three were used. The equilibrium constant was found by titrating a series of reactions containing H2O‚ HCl‚ and the unknown ester with only the last solution containing the unknown alcohol

Equilibrium In your text (Chang‚ 6th Ed) : Ch. 15 Chemical Equilibrium‚ esp. Section 15.3 Purpose: The Law of Mass Action will be examined via a series of samples using the same reaction‚ but different stating concentrations. The equilibrium constant‚ K‚ for each reaction will be calculated‚ demonstrating that K for a given reaction at a fixed temperature is a constant‚ independent of starting concentrations. Background: For a general reaction aA + bB ↔ cC + dD‚ the Law of Mass Action

In this experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color

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
