An energy diagram for a one step reaction with K eq < 1 is to be drawn. In the diagram the parts corresponding to the reactants, products, transition state, ΔG 0 and ΔG # are to be labeled. Whether the ΔG 0 of the reaction is positive or negative is also to be stated. Concept introduction: Energy diagrams are used to depict graphically the energy changes that occur during a reaction. The vertical axis of the diagram represents the energy of all the reactants and the horizontal axis, called reaction coordinate, represents the progress of the reaction from beginning to end. The reactants are shown in left and the products in the right. The transition state represents the highest energy structure involved in the particular step reaction. The overall ΔG # is the energy difference between the reactants and highest transition state and overall ΔG 0 is the free energy difference between the reactants and products. Every step in a reaction has a separate energy diagram. To draw: An energy diagram for a one step reaction with K eq < 1. To label in the diagram the parts corresponding to the reactants, products, transition state, ΔG 0 and ΔG # and to state whether the ΔG 0 of the reaction is positive or negative.

Question

Propagation of uncertainty. You have a stock solution certified by the manufacturer to contain 150.0±0.03 µg SO42-/mL. You would like to dilute it by a factor of 100 to obtain 1.500 µg/mL. Calculate the uncertainty in the two methods of dilution below. Use the following uncertainty values for glassware: Glassware Uncertainty (assume glassware has been calibrated and treat the values below as random error) 1.00 mL volumetric pipet 0.01 mL 10.00 mL volumetric pipet 0.02 mL 100.00 mL volumetric flask 0.08 mL Transfer 10.00 mL with a volumetric pipet and dilute it to 100 mL with a volumetric flask. Then take 10.00 mL of the resulting solution and dilute it a second time with a 100 mL flask. 2. Transfer 1.00 mL with a volumetric pipet and dilute it to 100 mL with a volumetric flask.

Chapter 6.SE, Problem 20EDRM

Interpretation Introduction

Interpretation:

An energy diagram for a one step reaction with K_eq < 1 is to be drawn. In the diagram the parts corresponding to the reactants, products, transition state, ΔG⁰ and ΔG^# are to be labeled. Whether the ΔG⁰ of the reaction is positive or negative is also to be stated.

What is the average mass of the 10 pennies? Report your value with correct significant figures. What is the error (uncertainty) associated with each mass measurement due to the equipment? What is the uncertainty associated with the average value? Note that the uncertainty of the balance will propagate throughout the calculation. What is the standard deviation of the 10 mass measurements? Explain the difference between the propagated uncertainty and the standard deviation. Which number would you use to describe the uncertainty in the measurement? Calculate the total mass of the pennies with associated uncertainty. Calculate the average density of a penny based on these data. Propagate the uncertainty values for both mass and volume in your calculations.
