Chem Equilibrium Lab

The Relationship Between Concentration and Shift in balance good Chemistry April 1th, 2012 Introduction: Some chemical answers pose to completion term most reactions proceed only to a state of balance wheel, where twain reactants and products exist to purposeher. In the state of offset, the judge of a rechargeable chemical reaction equals to the rate of its end 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 underline on the equilibrium and can alter its equilibrium position and thereby heighten the relative amounts of reactants and products (Davis et al., 2009). In this lab, a stress, which is produced only by the budge in concentration, is shown by the change of color during the reaction. To predict the go 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 clarified, 2012). At significan t elevations preceding(prenominal) sea leve! l, the port pressure is lowered, so the equilibrium shifts to the typeface 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.
