    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 constant, . When a reaction has not yet equilibrium, or to test whether it has, an equilibrium quotient can be obtained using the same formula to obtain the reaction quotient, to determine whether a reaction will proceed or isf it is at equilibrium.…

  • Chemical Equilibrium Lab

    This report will discuss multiple experiments regarding chemical equilibrium. Chemical equilibrium is when both reactants and products are both equal to each other. If one is not equal to each other, than the direction of shift will move to where equilibrium has been tampered with. Throughout all the labs, we observed that with different chemicals we have different directions of shift. From acids to bases, we see that direction of shift can vary which leads to different conclusions. We…

  • Essay On Effect Of Temperature On Amylase

    Introduction Enzymes are specialized proteins that act as catalysts. Enzymes are a key part of many biological processes because they are capable of lowering the activation energy of a chemical reaction. By lowering the activation energy enzymes are able to speed up reactions allowing for multiple chemical processes to occur at a faster rate in many living organisms. Enzymes work by binding to specific molecules called substrates. The enzyme observed in this experiment was amylase and its…

  • Beer's Law Lab

    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…

  • Adding Acetone To Test Tube 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…

  • Ksp Of Reaction Lab Report

    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^-…

  • Ice Calorimetry Lab Report

    leave one at room temperature. Allow the tubes to sit for a while, then compare the tubes and record any differences. If there is enough time, allow the tubes to warm/cool down to room temperature and record any observations. Dispose of the chemicals into the proper…

  • Bovine Serum Albumin

    albumin in 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…

  • Aqueous Reaction Research Paper

    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…

  • How Do Enzymes Affect Photosynthesis

    Enzymes are a biological catalyst. When a chemical reaction is taking place the enzyme works to lower the activation energy of a reaction. The activation energy is, the amount of energy that is required in order for a reaction to take place. Enzymes bind to reactant molecules. The enzymes hold these molecules in a way that makes the processes of the chemical bond-breaking and bond-forming take place more readily. A reaction can be either energy-releasing or energy-absorbing. Enzymes have no…
