Consider the following reaction (with a small amount of sulfuric acid added as a catalyst): Acetic acid + Isopentyl alcohol S Isopentyl acetate + Water The above chemical equation is balanced with coefficients of 1 in front of each compound. You are given the following information: Density (g / mL) Compound Quantity Molar mass State of used (g / mole) matter at room temp Liquid Acetic acid 2.0 mL 60.05 1.049 Isopentyl alcohol 2.0 mL 88.14 0.809 Liquid Isopentyl acetate 130.2 0.876 Liquid By the way, the sulfuric acid catalyst quantity is irrelevant to this problem. Given these quantities, calculate the THEORETICAL YIELD (i.e., the maximum number of GRAMS of isopentyl acetate that could be produced) for this reaction. Keep significant figure rules in mind! N.B. 1: Which of the reactants runs out FIRST? That would be the LIMITING REACTANT, and will be the one that will be used to determine the theoretical yield. N.B. 2: The answer is 2.4 grams of isopentyl acetate. Do your calculations verify this? Show all calculations on a separate sheet of paper.
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.
