Part A . What is the half-life for this reaction? Chymotrypsin is a digestive enzyme component of pancreatic juice that acts to break down proteins. The rate constant for the reaction that occurs when chymotrypsin reacts with its substrate N-acetylvaline ethyl ester is 1.7 x 10’s Express your answer to two significant figures and include the appropriate units. Half-life = 4.1 S Sub Previous Answers Correct Use the equation to calculate the half-life for a first-order reaction (t1/2), where k is the given rate constant. ti/2 = 0.693 0693 1.7×10- 11 4.1s = Part B to reach a concentration of 3.4 x 10M ? How long does it take for an N-acetylvaline ethyl ester concentration of 8.2 x 10M Express your answer in seconds to two significant figures. V AED 0 21 ? Submit Request Answer
