Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

Title : The movement of substances across a semi permeable membrane Objective : To study the movement of substances across a semi permeable membrane Problem statement : What factor influences the diffusion of substances through a semi permeable membrane? Hypothesis : The diffusion of molecules across a semi permeable membrane is based on the size of the molecule Variables: a) Manipulated : Size of solute molecules b) Responding : Colour of solution c) Fixed : Temperature and time

Dr. Sarvepalli Radhakrishnan‚ OM‚ FBA (5 September 1888 – 17 April 1975) was an Indian philosopher and statesman. He was the first Vice-President of India (1952–1962) and subsequently the second President of India (1962–1967). One of India’s most influential scholars of comparative religion and philosophy‚ Radhakrishnan is considered through his efforts to have built a bridge between the East and the West by showing that the philosophical systems of each tradition are comprehensible within the terms

History The Dominican Republic – Central America Free Trade Agreement is usually called CAFTA-DR. It is a free trade agreement that includes the United States and the Central American countries of Costa Rica‚ El Salvador‚ Guatemala‚ Honduras‚ and Nicaragua originally‚ and in 2004‚ the Dominican Republic joined the negotiations. Nearly all Central American exports to the United States were already tariff-free since the Caribbean Basin Initiative was first enacted in 1984. The agreement is a treaty

Other critics link The Strange Case of Dr. Jekyll and Mr. Hyde to a particular concern of the post-Darwinian world of the late nineteenth century: the fear that British society had become too civilized‚ too cultured. British men‚ it was feared‚ had become effete and no longer able to lead the British Empire. This fear that British men were not “manly” enough had the potential to destabilize England’s sense of leadership and cultural superiority. After all‚ the British defended their subjugation of

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered
