Equilibrium constant

In this project the aim is to determine the equilibrium constant (Kc) of a weak base when it reacts with a weak acid. The chemicals I wish to determine the equilibrium constant for are, Ethanoic acid (CH3COOH) and Propanol (C3H7OH). To accomplish this, the first question we must ask is, “what is an equilibrium constant and how is it determined”? There are 2 different types of equilibrium. The first, and the type we shall be using is known as homogeneous equilibrium which has everything present in the same phase. The usual examples include reactions where everything is a gas, or everything is present in the same solution. K is the universal equilibrium constant for reactions. There is also Kc and Kp, however Kp applies to reactions of gases,…

The purpose of this lab is to solve for the equilibrium constant of a reaction between iron (iii) ions and thiocyanate ions. The lab is divided into two parts: one section recording absorbance of reference solutions and the other part for the absorbance of test solutions. The reference solutions were created through the mixing of excess iron (iii) nitrate (Fe(NO3)3) with a known concentration of potassium thiocyanate (KSCN) in order to push the reaction to completion; the initial concentration…

human blood. It binds different types of drugs for delivery to various parts of the body. One of these drugs is warfarin, a blood anticoagulant. This research project’s focus was on the interaction between BSA and warfarin derivatives; our assumption was that the protein binding site has different affinities for different warfarin derivatives; this was to be determined by comparing the equilibrium constants (Keq) and the Gibbs’ free energies of a number of warfarin derivatives. To study this,…

Introduction Equilibrium is the concept that in a chemical reaction where both the forward and reverse reactions occur, equilibrium is reached when both reactions are occurring at the same rate, thus once a reaction is at equilibria both the forward and reverse reactions are occurring at the same rate. For a given Chemical Equilibrium at a given temperature, keq can be calculated that will be constant no matter the initial values of the reactants and products. For a reaction: the equilibrium…

Introduction: In this lab, seven test tubes containing solutions in equilibrium had different stresses added to them to examine the balance in each example. The purpose of the experiment was to indentify the details of shifting in equilibrium reactions and determine how the adding of a stress can affect a reaction. A chemical reaction that is in equilibrium is reversible, where a reactants can create products and products can go back to products. Equilibrium is reached when the rate of a…

CaCO3(s) ⇄ CaO(s) + CO2(g) Adding CaCO3 to the container will do absolutely nothing to the system, as it is a solid and is not taken into account when calculating the equilibrium constant. Increasing the pressure by adding argon gas will not affect the system. First of all, argon is an inert gas, which means it will not react with anything involved in this reaction. Since it does not react, it cannot affect the equilibrium constant. Increasing the pressure by decreasing the volume of the…

Discussion #1 All dominant strategy equilibria are also Nash Equilibria, but not all Nash Equilibria are also dominant strategy equilibria. Chp 7. Discussion #5 The nash equilibrium is E entering, and I not fighting. Using the web you get to this by doing backwards induction. No this threat is not credible. If E enters, I will still be better off not fighting. While fighting would prevent E from getting any profits, it would lower I’s profits from 50 to 10. Chp 8. Discussion #1 Chp 8.…

Aqueous-Minerals Reactions: Chemical reactions involving aqueous species and mineral species are heterogeneous and slower compared to aqueous species reactions, thus modeled as rate dependent chemical reactions. This means that when mineral species (N_m ) are not is equilibrium with the aqueous species, the minerals can either dissolve or precipitate. As shown in equation R11 of an example of calcite dissolution/precipitation, a mineral species (Calcite) is involved in a reaction with only…

contributed and empowered his beliefs because it was information that could be backed up with facts. To solve everyday life problems, Nash addresses most if not all of his issues as if it were a mathematical equation. If Nash is in a situation where he cannot logically figure out the answer, such as when he figures out his diagnosis, he tends to shut everyone out and has a minor emotional breakdown. The CMOP also states that there are three components to a person which are their cognitive…

Introduction Although, in general, salts are known for their solubility, not all types of salts completely dissociate in water. Some of them partially dissociates and creates a dynamic equilibrium due to the instances when their ions recombine to form the original salts. An example of this is potassium hydrogen tartrate (KHC4H4O6 or KHT). When KHT is placed in water, it partially dissolves and forms K+ and HC4H4O6- ions. This reaction is shown below: KHC_4 H_4 O_6 (s)⇄ K^+ (aq)+HC_4 H_4 O_6^-…
