Equilibrium In your text (Chang‚ 6th Ed) : Ch. 15 Chemical Equilibrium‚ esp. Section 15.3 Purpose: The Law of Mass Action will be examined via a series of samples using the same reaction‚ but different stating concentrations. The equilibrium constant‚ K‚ for each reaction will be calculated‚ demonstrating that K for a given reaction at a fixed temperature is a constant‚ independent of starting concentrations. Background: For a general reaction aA + bB ↔ cC + dD‚ the Law of Mass Action

Question 1 (Limiting Reagent) 15.00 g aluminum sulfide & 10.00 g water react until the limiting reagent is used up. [Atomic mass: H = 1.008‚ Al = 26.98‚ S = 32.07‚ O = 16.00] Here is the balanced equation for the reaction: Al2S3 + 6 H2O ( 2 Al (OH)3 + 3 H2S (i) Which of the two reactants is the limiting reagent? (ii) What is the maximum mass of H2S which can be formed from these reagents? (iii) How much excess reagent remains after the reaction is complete

Equilibrium Paper By: Brandon Walker ECO/561 July 14‚ 2014 Instructor: Mark Erenburg This paper was written to describe a real world experience in a free market were change occurred in supply or demand as a result of world events that led to the need for a move between two equilibrium states. I will also explain the process of how that movement occurred using behavior of consumers and suppliers while using graphs as indicated. Real Word Experience According to a United

Observing a Limiting Reactant An experiment was carried out to predict the limiting reactant in a chemical reaction between Magnesium and Hydrochloric acid‚ using the mole concept. Limiting Reactant: It is the reactant that will deplete or will be used up first during a chemical reaction. Limiting reactant also determine how long the reaction will last for. Balanced Equation: Mg + 2HCl = MgCl2 + H2 The balanced equation is needed to determine the mole ratio between the two reactants. From

substances react. By examining one specific example of stoichiometric determination‚ which is: “Stoichiometry and limiting reacting”‚ we found out the different mass proportions in which substance react. In this case‚ we used two common acids for this experiment (HCl‚ and H2SO4) and base NaOH Introduction: For this experiment‚ we use Stoichiometry and limiting reactant. The limiting reactant refers to the reactant that controls the amount of product that is

In this experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color

Nash Equilibrium and Dominant Strategies Nash Equilibrium is a term used in game theory to describe an equilibrium where each player’s strategy is optimal given the strategies of all other players. A Nash Equilibrium exists when there is no unilateral profitable deviation from any of the players involved. In other words‚ no player in the game would take a different action as long as every other player remains the same. Nash Equilibria are self-enforcing; when players are at a Nash Equilibrium they

What is a static budget? A static budget is a budget that does not change as volume changes. If a company’s annual master budget is a static budget‚ the budget for sales commissions expense will be one amount such as $200‚000 for the year. In other words‚ in a static budget the budgeted amount for sales commissions expense will remain at $200‚000 even if the actual sales during the year are $3 million‚ $4 million or $5 million. In contrast to a company’s static master budget‚ the company’s sales
