6. You'll use a stoichiometry calculation to predict the mass of aspirin you should obtain if all of the salicylic acid is converted to product. Since you'll do that calculation in today's lab, you'll use a different reaction to demonstrate that you can work stoichiometry problems unassisted: the condensation of ethanoic acid and cyclohexanol (in Question 1). Determine the mass of the ester product that should form when 2.23 grams of ethanoic acid is completely converted to ester with an excess of cyclohexanol. Show all three steps of the stoichiometry calculation (with units), and express your answer with units and the appropriate number of significant figures. ethanoic acid + cyclohexanol → ester product + water 60.05 g/mole 100.16 g/mole 142.19 g/mole

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.

41 SAM Pearson Learning: Ch 03R: Chemical Reactions and Chemical Quantities QUESTION Stoichiometry is a term chemists use to describe calculations that determine the relative quantities of reactants or products involved in a chemical reaction. Using stoichiometry, chemists can determine the amount of product that can be formed during a chemical reaction from a given amount of reactant. Chemists can also determine the amount of reactant needed to produce a desired amount of product using the same process. Select the missing conversion factor for the following set of calculations. Assume 12.3 grams of nitrogen dioxide, NO,, react with excess water. The problem requires that you determine the mass of nitric acid, HNO, formed from this reaction. 3 NO,(9) + H̟O(1) –→ 2 HNO,(aq) + NO(9) 2 m ol HNO, 63.02 g HNO, 3 mol NO, 12.3 g NO,x. 1mol HNO, := 11.2 g HNO, supnort
