activated complex – energy of the reactants

Question 15

if the para mentions precipate need to be careful and read if soluble in solvent or not. for ex ZnI2 is soluble in solution so what would be the reaction then

Answer 15

redox, not precipatw

Question 16

this type of reaction involves tranfer of protos

this would involve a ligan binding to a central atom with more than one coordinate covalent bond/donot atoms

Answer 17

chelate formation

Question 18

that the electric field is uniform bw electrodes means that the electric field lines

Answer 18

are equally spaced at both electrodes and between them

Question 19

which experimental condition is NOT needed to achieve reliable data for MM eq

Answer 19

rx is allowed to reach eq before measurement taken

Question 20

what are some assumptions of MM equation

Answer 20

• vi is measured under steady state
• solution pH remains constant at all times, else the data will be mixture Vo vs S cant dtermine Km, Vmax, may change emzyme function
• con of enzyme need lower than the substrate
