The cooking of an egg involves the denaturation of a protein called albumen. The time required to achieve a particular degree of denaturation is inversely proportional to the rate constant for the process. This reaction has a high activation energy, Ea=418kJmol1. Calculate how long it would take to cook a traditional three-minute egg on top of Mt. McKinley in Alaska on a day when the atmospheric pressure there is 355 torr. hours The catalyzed decomposition of ethanol at 325C has a rate constant of 4.00105Lmol1s1. A graph of the reciprocal of ethanol concentration versus time gives a straight line. The chemical equation for the reaction at this temperature is C2H5OH(g)C2H4(g)+H2O(g) If the initial concentration of ethanol is 0.024molL1, how long will it take for the pressure to reach 1.4 atm at 325C ? hours A tree killed by being buried under volcanic ash was found to have a ratio of carbon-14 atoms to carbon-12 atoms of 4.61014. The rate constant of the C14C12 decay is k=1.21104yr1 and the ratio of carbon-14 to carbon-12 is 1.21012 in a contemporary sample. How long ago did the eruption occur? t= yr
