Q1: The value of K, the equilibrium constant, is affected by which of the following (more...
Which of the following is true? When the value of Q is large, the equilibrium lies on the product side of the equilibrium reaction. When the value of K is large, the equilibrium lies on the reactant side of the equilibrium reaction. A small value of K means that the equilibrium concentrations of the reactants are small compared to the equilibrium concentrations of the products. A large value of K means that the equilibrium concentrations of products are large compared...
Which of the following will change the value of the equlibrium constant, K. for a given reaction? Increasing the concentrations of the reactants Increasing the pressure Increasing the concentrations of the products Increasing the temperature What is kinetic energy? the energy of an object's motion and position the energy from moving charged particles the energy stored due to an object's position or state the energy of an object in motion An equilibrium constant (K) much larger than I means that...
At a given temperature, the equilibrium constant for a certain reaction is 1 X 1014. Does this equilibrium favor products or reactants? Why? Select the single best answer. A very high value for the equilbrium constant favors product formation. O O Significant concentrations of both products and reactants are present at equilibrium. A very high value for the equilbrium constant favors reactant formation. A very low value for the equilibrium constant favors reactant formation. A very low value for the...

Which of the following statements is/are CORRECT? For a chemical system at equilibrium, the forward and reverse rates of reaction are equal. For a chemical system at equilibrium, the concentrations of products divided by the concentrations of reactants equals one. For a chemical system, if the reaction quotient (Q) is less than K, reactant must be converted to products to reach equilibrium.

I just did a lab on determination of an equilibrium constant through the reaction EtAc (aq) + H2O (sln) <-> EtOH (aq) +HAc (aq). For all initial concentrations, K was less than one. Which I know says that equilibrium favors reactants. One of the post lab questions is "Is the hypothesis that the equilibrium constant, K, really a constant not dependent on the initial concentrations correct? Explain your answer. " I am not sure how to answer this
Deriving concentrations from data The equilibrium constant, K, of a reaction at a particular temperature is detemined by the concentrations or pressures of the reactants and products at equilibrium. In Part A, you were given the equilibrium pressures, which could be plugged directly into the formula for K. In Part B however, you will be given initial concentrations and only one equilibrium concentration. You must use this data to find all three equilibrium concentrations before you can apply the formula...
Part A The equilibrium constant, K. of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium, For a gaseous reaction with the general form aA +B=cC+ DD the K, and Ky expressions are given by CDI K= A "B" (PE) K- Phosgene (carbonyl chloride). COClz, is an extremely toxic gas that is used in manufacturing certain dyes and plastics. Phosgene can be produced by reacting carbon monoxide and chlorine...
