The rate measured in an initial rate experiment must be classified as either average or instantaneous rate Concept Introduction: Chemical reactions proceed at a certain rate which is represented in terms of the change in concentration over a certain period of time. The rate can be expressed either in terms of a decrease in concentration of the reactants or an increase in the concentration of products. Average rate of a reaction can be defined as the difference in the concentrations measured at two different times whereas, instantaneous rate can be defined as the rate of a reaction at a particular instant in time.

Question

Chapter 11, Problem 11.22PAE

Interpretation Introduction

Interpretation:

The rate measured in an initial rate experiment must be classified as either average or instantaneous rate

Concept Introduction:

Chemical reactions proceed at a certain rate which is represented in terms of the change in concentration over a certain period of time.

The rate can be expressed either in terms of a decrease in concentration of the reactants or an increase in the concentration of products.

Average rate of a reaction can be defined as the difference in the concentrations measured at two different times whereas, instantaneous rate can be defined as the rate of a reaction at a particular instant in time.

In the video, we looked at the absorbance of a certain substance and how it varies depending on what wavelength of light we are looking at. Below is a similar scan of a different substance. What color BEST describes how this substance will appear? Absorbance (AU) Violet Blue Green Orange 1.2 1.0- 0.8- 0.6- 0.4- 0.2 0.0 450 500 550 600 650 700 Wavelength (nm) violet indigo blue green yellow orange red Red O Cannot tell from this information In the above graph, what causes -450 nm wavelength of light to have a higher absorbance than light with a -550 nm wavelength? Check all that are true. The distance the light travels is different The different data points are for different substances The concentration is different at different times in the experiment Epsilon (molar absortivity) is different at different wavelengths
