AAMC Chemistry Exam Practice Questions and Answers Consider the reaction rate described by the following equation. Rate = k[A]m[B]n The overall reaction is said to be second order when: A. k is constant, m=0, and n=0. B. k is constant, m=1, and n=1. C. k is constant, m=2, and n=2. D. k=2, and m and n are variable. - ANSWER-Answer Key: B The reaction is second order if the sum of the exponents m and n equals 2. In rate laws, k is the rate constant. The sum of the exponents equals 2 when...

BIO 311C FINAL EXAM QUESTIONS AND ANSWERS A+ GRADED Define monomers, polymers and macromolecules What reactions happen in condensation synthesis and hydrolysis? 1) condensation synthesis: MAKES polymers by releasing water molecules, condensation synthesis is important in anabolic processes (builds complex from simple) 2) hydrolysis BREAKS DOWN polymers into monomers by adding -H to one molecule and -OH to another (uses n-1 water molecules) while hydrolysis is important in catabolic proc...

A reaction had a ΔG > 0. For this reaction at equilibrium A) [products]/[reactants] > 1 B) [products]/[reactants] < 1 C) ΔH = -TΔS D) Keq > 1 E) B and D - ANSWER-B ([products]/[reactants] < 1) F is more probable than U because A) S water is increased B) van der Waals contacts are more favorable C) steric clashes are reduced upon folding D) all of the above E) A and B only - ANSWER-E ( A and B only) The entropy of water increases when the polypeptide chain adop...

1. If the delta G'° of the reaction A --> B is -40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from A to B. E For the reaction A --->B, delta G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 24 hours, analysis reveals the presence of 2 mmol of B, 8 mmol of A. Which is the mo...

Accuracy? - answer-Closeness of measurements to the TRUE VALUE of what is being measured Precision? - answer-Closeness of a SET of measurements How do you calculate Percent Error? - answer-I experimental-accepted I ____________________ x 100 accepted value Are zeros infront of non-zero digis significant? - answer-Nope! ex: 0.0071 is only 2 sig figs Are zeros at the end of a number and to the right of the decimal significant? - answer-Yep! ex: 9.100 is 4 sig figs Addition/S...
