Chem Equilibrium Lab

The Relationship Between Concentration and Shift in symmetry good Chemistry April 1th, 2012 Introduction: Some chemical responses rally to completion term most responses proceed only to a state of equilibrium, where twain reactants and products exist to purposeher. In the state of equilibrium, the step of a rechargeable chemical reaction equals to the rate of its chase away reaction, and the concentrations of its products and reactants remain un shortened (Davis, Frey, M. Sarquis, & J. Sarquis, 2009). However, changing the pressure, the concentration, or the temperature of one reaction is said to be producing a melodic phrase on the equilibrium and can alter its equilibrium position and thereby mixed bag the relative amounts of reactants and products (Davis et al., 2009). In this lab, a stress, which is produced only by the flip-flop in concentration, is shown by the change of color during the reaction. To predict the captivate of stress factors on equilibrium systems, the French chemist Henri Louis Le Châtelier developed a principle, which states that if a system at equilibrium is subjected to a stress, the equilibrium is shifted in the direction that tends to relieve the stress (Davis et al., 2009). This principle is named Le Châteliers principle and applied wide in reliable world.

Altitude sickness is mostly caused by the lack of oxygen, or more precisely, the lack of oxygenated hemoglobin in human luggage compartment (Science clarified, 2012). The interaction of hemoglobin and oxygen is expressed thereof: Hb(aq) + 4O2(g) ? Hb(O2)4(aq) (Science cl arified, 2012). At significant elevations ! higher up sea level, the port pressure is lowered, so the equilibrium shifts to the incline with fewer moles of gas, which is left, tally to Le Châteliers principle. Therefore, the reverse reaction is favored at high altitude; there is not enough oxygenated hemoglobin to feed to the bodys cells and tissues, so a individual tends to get altitude sickness.
