NOBr(g) decomposes to form NO and Br2 by the reaction 2 NOBr(g) → 2 NO(g) + Br₂(g) - It is found that the reaction is second order in NOB. The rate constant has been found to be 0.170 M-1 s-1. In a situation where the initial concentration of NOBr in a vessel is 0.560 M, how long will it take for the concentration of Br2 to reach 0.190 M? (Assume, of course, that there was no Br2 in the vessel to begin with.) Report your result in seconds with one decimal place but do not put units in the answer box.
One type of gas mixture used in anesthesiologyis a 50%/50% mixture (by volume) of nitrous oxide (N2O) and oxygen(O2), which can be premixed and kept in a cylinder for later use.Because these two gases don’t react chemically at or below 2000 psi, attypical room temperatures they form a homogeneous single gas phase,which can be considered an ideal gas. If the temperature drops below-6C, however, N2O may begin to condense out of the gas phase. Thenany gas removed from the cylinder will initially be nearly pure O2; asthe cylinder empties, the proportion of O2 will decrease until the gascoming from the cylinder is nearly pure N2O. In another test, the valve of a 500 L cylinder full of the gas mixture at 2000 psi (gauge pressure) is opened wide so that the gas rushes out of the cylinder very rapidly. Why might some N2O condense during this process? (a) This is an isochoric process in which the pressure decreases, so the temperature also decreases. (b) Because of the rapid expansion, heat is…
