Solubility equilibrium

A chemical reaction’s rate is described by the amount of product formed. Substances that increase that rate are called catalysts. Catalysts are often proteins called enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points. Enzymes are effective by reducing the activation energy. The enzyme tyrosinase is located in melanocytes. These are cells that produce the pigment melanin. Melanin gives skin, eyes,…

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 role of enzymes play a large role in the survival of organisms through catalysis of reactions that keep them alive and functioning. The purpose of this experiment was to measure reaction activity over time and how substrate concentration affects their activity level. A supernatant was made through the dilution of blended potato extract. Then the supernatant was mixed with catechol and the reaction rate was measured in units of absorbance through a spectrophotometer every 30 seconds for ten…

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 container will change the system by causing more…

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…

Aim: This is an investigation to establish the effect of different temperatures (from 0°C -100°C) on the production of oxygen gas in a potato catalase reaction, using hydrogen peroxide as a substrate. The oxygen gas produced will be measured using a gas pressure sensor. Introduction: Enzymes are proteins, known as biological catalysts that increase the rate of reaction in a biochemical reaction without being chemically altered. The human body consists of various different types of enzymes,…

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…

his work in mathematics. While Nash is at a bar with some of his fellow students, they try to come up with a strategy to talk to some woman there. As they discuss some possible approaches, Nash creates an idea, which becomes known as the Nash Equilibrium and publishes a piece on it. This game theory basically states that if there are two people in a situation and one person has taken the other person's perspective into account and is a making the best decision that they can; and the second…

The second argument Dawkins makes is that religion and God create a false hope to all those who put their faith in it (Dawkins 2014). He believes religion in the face of God encourages people to believe in a higher being who oversees everything and plays are part in the lives of each person on earth (Dawkins 2014). God and religion also creates a false hope that there will be white gates waiting for the after death (Dawkins 2014). Dawkins believes that God is a being that controls and influences…

above-mentioned changes has been done by John Nash and his followers who developed the concept of Game Theory and Nash Equilibrium in particular. For the purpose of this essay, the Game Theory would be defined as “study of decision-making where several players must make choices that potentially affect the interests of the other players” (Turocy and Stengel, 2001). The Nash’s equilibrium would be referred as ‘the combination…
