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

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

watch the news there seems to be something related to drug trafficking. In doing my research I found that a lot of drugs come into the U.S. from many different places‚ and by so many different ways that you would not imagine. I always thought drug trafficking had to do with the transport of drugs from state to state‚ but in doing my research I soon found that it goes way deeper than that. So in doing this research I plan and hope to be more educated on this topic. Ways that I plan on refining
