The quantum yield of light-induced chemical reactions (called photochemical reactions) measures the efficiency of the process. The quantum yield, ϕ, is defined as:ϕ=numberofreactioneventsnumberofphotonsabsorbed. Suppose a quantum yield for the reaction CH3X→CH3+X is ϕ = 0.41. A cuvette containing a solution of CH3X is irradiated with 280-nm with a power of 885 mWfor 10.0 minutes.

Part A

Assuming total absorption of the light by the sample, what is the maximum amount (in moles) of CH3X that breaks apart?

Express your answer to two significant figures.

=

Data was obtained from a chemical process where the percent yield of the process is thought to be related to the reaction temperature (in degrees F). We would like to see if the temperature can predict the yield. The regression equation we obtained was Y = 17+ 2X. Use this information for all the parts. Part 1: What would X be here?

Yield of Chemical Process Two catalysts were analyzed to determine how they affect the mean yield of chemical process. Specifically, catalyst 1 is currently used; but catalyst 2 is acceptable. Because catalyst 2 is cheaper, it should be adopted, if it does not change the process yield. Two tests were run in the pilot plant. Eight samples of each type of catalyst were randomly and independently selected from the pilot plant, and the chemical process yield were recorded. The data...
