Imagine five people working together to wash a stack of very greasy dishes. The first two clear the table and hand the dishes to the third person who washes them and hands them on. The last two persons dry and stack them. Which step is likely to be the rate determining step In the light of your answer, discuss how the rate of the overall process would be affected if a sixth person joined the group (a) as a table clearer (b) as a second dishwasher (c) as a dish dryer.

Fatty acid diethanolamides (FADAs) are used in certain household textile washing and hand dish-washing formulations. The presence of coconut diethanolamides (CDEAs) with an alkyl chain between 7 and 15 C units has been reported in municipal wastewaters in Germany at levels of 111—124 i,g L 1 [31] in influent and 14 i,gL 1 in effluent indicating approximately 90% elimination, while the monitoring of CDEAs in a Swedish WWTP indicated significantly lower removal (about 40%). Other studies [8,29,32,33] reported levels up to 470 xg L-1 in raw influents (Table 6.1.7). Very low concentrations found in effluents indicate efficient elimination (>96%), whereas nothing is known about the formation of persistent metabolites. 

When washing dishes by hand, do so in a sink or large pot filled with soapy water. Quickly rinse under a small stream from the faucet. 

The greasy tails can dissolve in each other, forming a spherical structure called a micelle. This is how soaps work in washing your hands or doing dishes.

Clean all apparatus and your lab station. Put the wire, NaCl, and weighing paper in the containers designated by your teacher. Pour the water from the beakers into the sink. Scrub the cooled evaporating dish with soap, water, and a scrub brush. Be certain that the gas valves at your lab station and the nearest lab station are turned off. Be sure lab equipment is completely cool before storing it. Always wash your hands thoroughly after all lab work is finished and before you leave the lab.
