An elevated level of the enzyme alkaline phosphatase (ALP) in human serum is an indication of possible liver or bone disorder. The level of serum ALP is so low that it is very difficult to measure directly. However. ALP catalyzes a number of reactions, and its relative concentration can be determined by measuring the rate of one of these reactions under controlled conditions. One such reaction is the conversion of p-nitrophenyI phosphate (PNPP) to p-nitrophenoxide ion (PNP) and phosphate ion. Control of temperature during the test is very important; the rate of the reaction increases 1.47 times if the temperature changes from 30 C to 37 C. What is the activation energy for the ALP-catalyzed conversion of PNPP to PNP and phosphate?

Consider the reaction below. If the concentration of the nucleophile is doubled, the rate of the reaction will If the concentration of the alkyl halide is doubled, the rate of the reaction will H₂O x CI OH (c) double, not change (d) triple, triple (a) not change, double(b) double, double (e) not change, not change

A reversible step in a mechanism indicates that the step is the rate -determining step in the mechanism. True False

Consider the given reaction in which NC−NC− is the nucleophile and CH3CNCH3CN is the solvent. The reactant molecule has a structure with solid and dashed wedge bonds. A solid wedge () is used to show the bond that is above the plane of the paper, and a dashed wedge () is used to show the bond that is behind the plane of the paper. Draw the product of the following reaction:
