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

rate of the forward reaction and the rate of the reverse reaction equal each other. At this point‚ the concentrations do not change with time. These reactions are said to be in equilibrium. Equilibrium is depended on a particular temperature‚ and the concentrations of reactants and products have to follow a rule demonstrated by the equilibrium constant Kc. The equilibrium concentrations that will be studied is the reaction between iron (III) ion and thiocyanate ion: The mixture of Fe3+ and SCN-

1.) What is Due Process? a. Due process is a way to guarantee any one facing prosecution in the United States their human rights to the constitution. All defendants must be provided with a fair opportunity to participate in all proceeding stages. The 5th and 14th amendments discuss due process. The 5th amendment applies only to the federal government and its courts and agencies. The 14th amendment extends the due process to all state government‚ courts and agencies. This is how and why laws are applied

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete.
