Equilibrium constant - Free Essay Examples and Topic Ideas

The equilibrium constant is a measure of the extent of a chemical reaction at equilibrium. It is the ratio of the products’ concentration to the reactants’ concentration at equilibrium, with each concentration raised to the power of its stoichiometric coefficient. The equilibrium constant is a thermodynamic property that determines the direction and position of equilibrium. It is widely used in chemistry to determine the composition of equilibrium mixtures and to predict the feasibility of reactions.

    This will help ensure that the results of the experiment are reliable and ensure that the acids react with the magnesium and not the formulated oxide layer. The Acids: Choice of acids and their varying strengths was based upon the Bronston-Lowry theory. According to the Nuffield Advanced Chemistry Students' Book, acids that ionise completely at moderate dilutions are called strong acids. Consequently they tend to have a large Ka (dissociation constant) value. Weak acids interact very little with water therefore…

    ABSTRACT Thermodynamic values can be determined using the Vant Hoff isochore method. This method entails the use of equilibrium systems to determine the change in enthalpy of the solution, which can b related to the change in internal energy of the solution. The van't Hoff isochore relates the equilibrium constant of a chemical reaction at one temperature to the equilibrium constant of the same reaction at a different temperature, allowing it to be worked out for all temperatures if it…

    I. INTRODUCTION The solubility product constant, Ksp​, is the equilibrium constant for a solid substance dissolving in an aqueous solution. It represents the level at which a solute dissolves in solution. A more a substance dissolves, the higher the Ksp value it has. In this experiment, a system of a sparingly soluble salt in water is studied. From the solubility information at various temperatures, the changes in standard enthalpy, standard entropy, and standard free energy were established. II. THEORETICAL BACKGROUND…

    Identifying an unknown compound can be a difficult task. In identifying a compound, researchers often measure several physical properties: melting point, boiling point, density and observes a few chemical properties: reactivity, acidity, basicity of the compound. The reason for determining several chemical and physical properties of the compound is that it is quite possible for two different compounds to have a few physical and or chemical properties in common; but it is highly unlikely for the two compounds to have…
