WebFeb 16, 2012 · First set up the ICE table and fill in the information from the problem. Next, make an X value representing the change in concentration when it shifts to the equilibrium. Here is where one assumption comes in. It shifts to the right because the concentration values are zero on the right hand side. WebAug 30, 2024 · 3. Identify the assumption. When you know the premise and conclusion, it is easy to figure out the assumption. As discussed before, the assumption is a hidden or unstated part of given statements. Putting in other ways, it is the connection between premise and the conclusion.

WebJan 23, 2024 · One reasonable assumption is that the initial concentration of Pb 2+ is very close to its equilibrium concentration. If this assumption is correct, then the following approximation is reasonable [Pb2 +] = 0.10 + x ≈ 0.10 Substituting this approximation into Equation 6.7.1 and solving for x gives (0.10)(2x)2 = 0.4x2 = 2.5 × 10 − 13 x = 7.91 × 10 − 7 WebIt’s best to make a prediction on Sufficient Assumption questions, to save time in the choices and make the tempting choices look less tempting.

The expression for K a is written by dividing the concentrations of the products by the concentrations of the reactants. Plugging in the values at equilibrium into the equation for K a gives the following: K a = x 2 0.150 − x = 1.6 × 10 − 2. shrimp aristotle recipe
