Given the reaction at 300K: 2A(g) = 3B(g) + C(g) Kc = 5.5 x 10-5. If 12.0 moles of A is added to a 3.0L container (hint, you need molarity not moles in your ICE table), what will the concentration of A be at equilibrium? Neglect x for this problem. Report your answer to 2 significant figures. Answer: 3.8
Given the chemical reaction below, A(aq) + 2 B(aq) ⇌ C(aq) + D(l) the equilibrium constant for the reaction is Kc = 0.8. The reaction mixture at equilibrium contains 1.47 mol of A, 1.84 mol of B in a 1.00 L flask. What is the concentration of C in the equilibrium mixture? Only enter the numerical value with three significant figures in the answer box below. Do NOT type in the unit (M).
Write the equilibrium-constant expression for the reaction A(s)+3B(l)<------->2C(aq)+D(aq) in terms of [A], [B], [C], and [D] as needed. Kc=? *Kc, which is sometimes symbolized as Keq, denotes that the equilibrium constant is expressed using molar concentrations. For this question, Kc means the same thing as Keq.
Consider the following reaction: HC2H3O2(aq)+H2O(l)⇌H3O+(aq)+C2H3O−2(aq) Kc=1.8×10−5 at 25∘C If a solution initially contains 0.180 M HC2H3O2, what is the equilibrium concentration of H3O+ at 25∘C? Express your answer using two significant figures.
Consider the balanced chemical equation for this equilibrium reaction: A (aq) + B (aq) = AB (aq) To determine the equilibrium constant for this reaction at 298 K, a student mixes two solutions together and allows them to react: • 10.0 mL of 0.60 M A (aq), and, • 40.0 mL of 0.25 MB (aq). When this solution reaches equilibrium, the student measures the equilibrium concentration of AB in the 50.0 mL solution: [AB]E = 0.10 M. Which values should...
