At 500 °C, cyclopropane converts to propene. The concentrations of cyclopropane were measured at a series of times after the reaction started. Using the data given in the spreadsheet on moodle, determine what order (zero, first or second) the conversion is and find the value of k. Be sure to attach your graph(s). What was the original concentration of cyclopropane? What is the half life of this conversion? Read Chapter 21 Section 10 (third edition) or Section 4 (fourth edition) or Chapter 19 Section 5 (fifth edition)about radio carbon dating. The decay is first order and the half life of 4C is 5730. years Using human feces found in a cave in Oregon, archaeologists have determined that humans lived in the cave 13500 years ago 14 f 14Cnou:4Coriginal (jC ) in the feces sample? . What was the ratio o Chlorine destroys the Earth's ozone layer by the following precess. ClO + O â Cl + O2 The O atoms in the second step come from the decomposition of ozone by sunlight: A. What is the net reaction for these three steps? B. What is the role of the chlorine atoms? C. Are there any intermediates? If yes, identify.
