can someone help me with this lab please

LAB #3 - Chemistry 30 Part D- Equilibriums Equilibrium Concepts - An Introduction If equilibrium is to be achieved, opposing reactions must take place in a closed system at the same rate. The two reactions, known as forward and reverse reactions, may be represented by a general equation such as: forward AB C reverse When the forward and reverse reactions are taking place at the same rate, the system is said to be in a state of dynamic equilibrium. During such a state, no changes are occurring in the macroscopic properties of the system in spite of the fact that changes are occurring at the molecular level. In this lab, you will construct an analogue for an equilibrium reaction in which the reactants are products are represented by the water in two separate graduated cylinders. The volume of water exchanged will represent changes in the concentrations. After you have read over the Procedure for the exercise, try to predict the outcome before actually doing it. buta sa 00 OMAINS Show cometen sowWider Na dlometer strow in cylinder B Numbar al transfers Munawwl Tronx Maluma at watercolor (un) 250 volume materiale UNA valueria ufurater cylinder A (me) 200 D D 1 BEM 11 DER 20 2 220 15.

Join each set of points with a smooth curve. Title your graph and label your axis with a name and units. a Questions 1. The water volume in the experiment is acting like the concentration of reactant in a chemical reaction. By observing your graphs, describe the curve (changes in "concentration") and the corresponding rates which occur in each curve up to the point where the extra 5 mL of water was added. 2. Describe the change which occurs on the graph for "A" at the point where the 5 mL of water is added. 3. What significance (in regard to volume) can be attributed to: the point where the two curves meet (Data Set B), b. the first flat portion of the two curves, and C. the second flat portions of the curves? ) Accessibility: Investigate 17 EE 4. After the 5 mL of water is added to cylinder 'A', what trend occurs with the final volume in cylinder 'B'? 5. What is the evidence that equilibrium has been established if a. the data for the water transfer are observed, or b. the plotted data (graph) are observed? 6. Why is this particular system called "closed?" 7. The additional 5 mL of water constitutes a "stress' on the system. a. What analogous stress would be involved if the system really represented a chemical reaction in equilibrium? b. Name two other "stresses" which could be imposed on a chemical system. 8.
