Reaction Mechanisms p.1&2 (Answer Key) Want to play around with the reactions and rate PHET Simulation? A catalyst actually increases the rate of reaction by lowering the amount of energy needed to start the process. A catalyst will either increase or decease the rate of reaction based on what type of material is used. (A) a greater rate of reaction and a greater yield of SO 3 at equilibrium. (B) a greater rate of reaction and the same yield of SO 3 at equilibrium. (C) a lesser rate of reaction and a lesser yield of SO 3 at equilibrium. Worksheet — Reaction Mechanisms The sequence of elementary steps that leads to the formation of products is called the reaction mechanism. There are three types of elementary steps: unimolecular bimolecular termolecular A product A+A or A+B product A+A+A or A+A+B—þ product rate = k[A] rate = or rate = or k[A] [B] etc. a). Describe the change in the rate of reaction when the substrate concentration is increased (assuming a fixed amount of enzyme and ample cofactors): b). Explain why the rate changes the way it does: Temperature Higher temperatures speed up all reactions, but few enzymes can tolerate temperatures higher than 50-600C. reaction rates multiple choice questions with answers.pdf REACTI ON RAT ES MU LTIPLE CHOI CE QUESTI ONS WIT H AN SWER S Note: The letter i n bold is the corr ect ans wer Part B – Reaction Rates. Using the reaction coordinate diagram above, draw a new curve that shows how a catalyst would affect the reaction pathway. Place a checkmark next to the actions that would most likely increase the reaction rate. ____ Lowering the temperature of the reactants. ____ Dissolving two solids in water before mixing them

(A) a greater rate of reaction and a greater yield of SO 3 at equilibrium. (B) a greater rate of reaction and the same yield of SO 3 at equilibrium. (C) a lesser rate of reaction and a lesser yield of SO 3 at equilibrium.

Potential Energy Diagram Worksheet ANSWERS 1. Which of the letters a–f in the reaction? __f__ 6. Is the reaction exothermic or Reaction Rates and Potential Energy Diagrams 1. Chemical reactions occur when reactants collide. For what reasons may a collision fail to produce a chemical reaction? b). Explain why the rate changes the way it does: Temperature Higher temperatures speed up all reactions, but few enzymes can tolerate temperatures higher than 50-600C. The rate at which enzymes are denatured (change their shape and become inactive) increases with higher terhperatures. a). d) If reaction #1 is heated to 35 C the rate increases to 4.8x10-4 M/sec. What is the activation energy of this reaction? e) At what temperature would the reaction rate double from 25C? 11) A cook finds that it takes 30 minutes to boil potatoes at 100 C in an open sauce pan and Predict how addition of a reactant or product will affect the forward and reverse reaction rates, and once this new system reaches equilibrium how the reactant and product concentrations will compare to the original system at equilibrium.

Worksheet 1.1 - Reaction Rate Calculations 1. A chemist wishes to determine the rate of reaction of zinc with hydrochloric acid. The equation for the reaction is: Zn(s) + 2HO(aq)-f H2(g) +ZnC12(aq) A piece of zinc is dropped into 1.00 Lof 0.100 MHCI and the following data were obtained: T · ( )() f .

The average reaction rate of 0.0300 moles C 4H 9Cl consumed per liter per second is reasonable based on the starting and ending  Worksheet: Reaction Rates. Name______________. 1. A study of reaction. is called chemical . 2. Reaction rate refers to how quickly or slowly the. disappear  Likewise, the rate of a chemical reaction is a measure of how much reactant is consumed, Reaction rates are therefore determined by measuring the time dependence of some Answer: 1.05 × 10−6 mol/L/s, N2 and 3.15 × 10−6 mol/L/s , H2. The reaction rate law expression relates the rate of a reaction to the concentrations of the reactants. Each concentration is expressed with an order ( exponent).
