Assume every breath a person took is 0.5L of air, figure out how many grams of Oxygen you consume at every breath. Now assume that you breathe 30 times per second, figure out how long it took for you to consume all the oxygen in a sealed room of 125m^3 room (assume the initial partial pressure of O2 in air is 0.21 by mole fraction).
Oxygen at 150 K and 41.64 atm has a tabulated specific volume of 4.684 cm3/g and a specific internal energy of 1706 J/mol.
what is the rate constant for this reaction at 398 K ? I know that the answer is 1.2 s-1 but I don't know how to get it . Can anyone explain it to me please?
