acetic acid is 25 ml and alcohol is 20 ml
The synthesis of an ester by the reaction of a carboxylic with an alcohol is an equilibrium reaction. H - R-OH HO ROH R OR, Recall from general chemistry that, according to Le Caiclista principle, an equilibrium can be shifted toward greater product formation by using an excess of reactant or by removal of a reaction product as it forms. 1. Are any products removed during the reaction period (the...

If the reaction between iron(III) ion and thiocyanate ion yielded an equilibrium concentration of 0.30 M for each of these ions, what is the equilibrium concentration of the red iron(III)-thiocyanate complex? (Hint: The equilibrium constant for the reaction is in the Background section.) Show your work 3. In the reaction below, NH3(g) + H2O(1) - NH; +H30+ the equilibrium constant is 10-34. Is this reaction likely to take place? Explain your answer. iron(III) and thiocyanate ions, the equilibrium expression...

Learning Goal: Develop problem-solving skills wing chemical equilibria and oplying Le Chatter's principle Solving problems with chemical equilibrium If you know the basic principles of chemical equilibrium, you can analyze and predict reversible reactions. To analyze any reversible reaction, follow these problem-solving steps: 1. Identify the reactants and products for the given chemical reaction. 2. Draw a diagram of the reaction to better understand what is happening 3. Identify how increasing or decreasing a product or reactant stresses the equilibrium...

Le
Chateler's principle
In the chart below: • Indicate the color of each solution as darker or lighter than the control after the addition of the specified substance. • Indicate the direction the equilibrium shifted as "toward products" or "toward reactants" based on the color change. • Based on the direction of the shift, indicate the substance(s) that increased which will either be the two reactants present on the reactant side of the equilibrium equation or the complex present on...
