The rate equation for the second-order reaction of an enzyme (e) and its substrate (s) is vo = keat le][s] near the where it is the second-order rate constant, which can be used to compare catalytic efficiencies. enzymes with a diffusion-controlled limit are said to have achieved catalytic perfection. what is the diffusion-controlled limit in an aqueous solution? 10-4 to 10-8 m-s-1 107 to 10% m s 10 to 10-sm 109 to 1010 m.5-1 o 10-7 to 10-'m-'s-1 10% to 10º m/s o 10% to 10% m-1-1

When a septic tank backs up a goes in to clean it out

Voltaic cells produce a positive overall charge. what does this indicate? a. the reaction is likely to be endothermic. b. the reaction is spontaneous. c. the reaction is not likely to occur. d. the reaction is not spontaneous.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
