2 This is a true story. A lawyer in Bloomington, Indi- ana, wanted to impress a judge with the high num ber of PCB molecules that a typical person takes in with each breath. He called Prof. Hites for this fact but he did not have this information at hand. How. ever, a student of his had recently determined that the flux of PCBS from the atmosphere to Blooming- ton's surface averaged 50 ug m year '. You may assume that the area of Bloomington is 100 square miles, that the deposition velocity of PCBS is 0.3 cm/s, and that the molecular weight of PCBS is 320. What would you tell the lawyer? -2

In a study of the gas phase decomposition of phosphine at 120 °C PH3(g) 1/4 P4(g) + 3/2 H2(g) the concentration of PH3 was followed as a function of time. It was found that a graph of In[PH3] versus time in seconds gave a straight line with a slope of -2.65×10 2 s-1 and a y-intercept of -2.78 Based on this plot, the reaction is v order in PH, and the half life for the reaction is seconds. zero first second
