Investigating the effect of temperature on the position of the equilibrium among carbon paper monoxide gas in excess aqueous chloride ions Abdul Rahman Khalifeh Aim To make do the counterchange of the position of equilibrium between Co2+ (aq) of nearness of 0.3 jetty L-1 and Cl- of closeness 3.0 gram molecule L-1 when placed at temperatures of 0°C, 95°C and 25°C. Hypothesis Since this reaction is endothermic, as temperature increases the equilibrium will play to the right according to Le Chateliers principle. Water would terminate the equilibrium to the left and the HCl would move the equilibrium to the right according to Le Chateliers principle. Variables aquiline variable(s) | Independent Variable(s) | Controlled Variables | The position of the equilibrium which is monitored by the colour change of the solution| The temperatures of 0°C, 25°C and 95°C. at which the reaction takes place| Same submerging of aqueous chloride ions (3.0 mol L-1)| | | 6 test tubes of the same size, shape and volume.| | | Same concentration of aqueous cobalt ions (0.

3 mol L-1)| | | The same digital correspondence to 4 signifi fuelt figures after the decimal foreshadow in do to have the same uncertainty for alto purporther measurements taken | | | The same of solution in altogether cases| apparatus starter| Chemicals| Equipment| (3) evidence tube| 600 g of Ice| gawk| (3)50 cm3 Beaker| 30.0000 g of CoCl2.6H2O| Test tube holder| Graduated cylinder- carbon cm3| Concentrated HCl | digital balance to 4 significant figures| conelike Flask 100cm3| | bunsen burner burner| | | Thermometer| Method for the Control of Variabl es In order to obtain the consummate cont! rol of variables we must control all other factors poignant the position of the equilibrium. Hence the concentration of aqueous chloride ions and aqueous cobalt ions must be fixed and this can be make by measuring the mass of CoCl2.6H2O accurately by utilize a digital balance to 4 significant figures. In order to control the...If you want to get a fully essay, order it on our website: OrderEssay.net
