Complete hydrolysis of 25 mM ethyl acetate in an enzyme esterase catalyzed reaction is carried out in a 40 mM NaCl solution buffered by 0.2 M Tris-Cl, pH 9.1. What is the pH at the end of the reaction? (For Tris base, which is the abbreviation for Tris (hydroxymethyl) aminomethane, pKa = 8.1; for acetic acid, pKa = 4.76)
Complete hydrolysis of 25 mM ethyl acetate in an enzyme (i.e., esterase)-catalyzed reaction is carried out in a 40 mM NaCl solution buffered by 0.2 M Tris-Cl, pH 9.1. What is the pH at the end of the reaction? (For Tris base,
Hers's a question im not sure how to do Write a mechanism for the acid-catalyzed transesterification reaction of ethyl acetate with 1-butanol, which gives butyl acetate. Thank you soo much!!!!!!!!!!!!!!!!!!!!!!
The hydrolysis of ethyl acetate (CH3COOC2H5) by sodium hydroxide yields ethanol (C2H5OH) and sodium acetate (NaO2CCH3) by the reaction shown, which follows second order kinetics. In an experiment 500 mL of 0.1 M ethylacetate in
At body temperature (37C), K of an enzyme-catalyzed reaction is 2.3x10^14 times greater than k of the uncatalyzed reaction. Assuming that the frequency factor A is the same for both reaction, by how much does the enzyme the E^a?
One of the concerns about the use of Freons is that they will migrate to the upper atmosphere, where chlorine atoms can be generated by the following reaction: CCl2F2 --> CF2Cl + Cl Chlorine atoms can act as a catalyst for the
Okay so if i have two enzyme catalyzed reactions: 1) delta g of the ES = -22kJ/mol 2) delta g od the ES = 42 kJ/mol Is this first reaction going to have a higher reaction rate because the of the negative delta g, because doesnt a
