One application of adsorption on surfaces is to measure the ability of acti- vated charcoal to adsorb acid. (Activated charcoal, a form of treated carbon, is very porous and is used to adsorb impurities from water. Its use in aquar- iums typifies this behavior.) In a lab experiment, a student mixes a given amount of powdered charcoal into a series of acetic acid solutions. The acetic acid solutions have different initial concentrations. Some of the acid is ad- sorbed onto the charcoal. By taking aliquots after equilibrium is established, the student determines the change in acid concentration. Plot a Langmuir isotherm for the experimental data and determine the equilibrium constant for the adsorption. The experimental data are as follows: Original concentration (M) 0.7001 Change in concentration (M) 0.3694 0.1515 0.0437 0.0169 0.00665 0.00588 0.00553 0.00283 0.00153

the equilibrium constant (K) is a quantitative measurement of theextent to which a chemical or physical reaction proceeds to completion. If two reactants ofknown initial concentration are mixed and then the concentrations of the products aremeasured once equilibrium has been established, then the equilibrium constant can becalculated using an ICE table.In this experiment you will measure the equilibrium constant for the formation of iron(III)thiocyanate from the iron(III) cation and thiocyanate anion:Fe3+(aq) + SCN-(aq) FeSCN2+(aq)The product, FeSCN2+, is intensely red, which means that its concentration can be measured byusing an ultraviolet-visible (UV-vis) spectrophotometer. So long as a solution is not tooconcentrated, the absorption of light at a particular wavelength by a chemical species isdescribed by Beer’s Law:A = εℓ[X] where A = absorption of light (unitless number)ε = molar absorptivity constant (cm-1 M-1)ℓ = path length (cm)[X] = concentration (M)The path length for our…

a. Suppose the reaction system CH4 (g) +20₂ (9) — CO2 (g) + 2H₂O(1) has already reached equilibrium. The position of the equilibrium was shifted by removing any liquid water from the system. Choose the correct effect on equilibrium (it will shift to the right, will shift to the left, or it will not be affected). O It will shift to the right. O It will shift to the left. O It will not be affected. b. Suppose the reaction system CH4 (9) +202 (g) ⇒ CO2 (g) + 2H₂O(1) 2 has already reached equilibrium. The position of the equilibrium was shifted by adding CO₂ to the system by dropping a chunk of dry ice into the reaction vessel.

Which of the following statements is a true statement concerning a reaction that has reached a state of equilibrium? A system has reached equilibrium when the concentrations of reactants and products remain constant. A system has reached equilibrium when the reaction has stopped and no more products are formed. A system has reached equilibrium when the rate constant for the forward reaction equals the rate constant of the reverse reaction. A system has reached equilibrium when the concentrations of reactants and products correspond to the stoichiometric ratios determined by the balanced equation.
Hydrogen peroxide, H₂O₂, has a density of 1.45 g/cm³ and decomposes spontaneously but slowly. The decomposition reaction will proceed at a faster rate if iodide ion, a catalyst, is added. The steps for the catalyzed reaction are: H₂O₂(aq) + (aq) → H₂O(l) + Ol-(aq) OO H₂O₂(aq) + Ol(aq) → H₂O(l) + O₂(g) +1-(aq) a. What is the net reaction? b. If 10.00 mL of H₂O₂ undergoes this reaction, what mass of oxygen is produced? c. If the reaction has an 85.5% yield, what mass of oxygen is actually produced?

The following system is at equilibrium in a closed vessel: 4 HCl(aq) + MnO2(s) ⇆ MnCl2(aq) + 2 Cl2(g) + 2 H2O(l) Various stresses are applied to the system as illustrated in the chart. Drag the appropriate label from the list below that indicates how the system responds to each stress. Each label can be used more than once.
These are three parts and it counts as one question.
True/False. Explain your answer in one sentence or less. In an equilibrium process, the concentrations of products and of reactants are equal. The value of the equilibrium constant for a given reaction depends on the initial concentrations of reactants. Large value for equilibrium constant K means the reaction will be less complete at the equilibrium point. The concentration of a pure solid is left out of an equilibrium constant expression but a pure liquid is included.
