2NO+O2->2NO2
a) During a certain interval of time the variation of oxygen O2 moles is -5mol. Calculate the variation of the number of moles of nitrogen monoxide NO and that of nitrogen dioxide NO2 during the same interval of time.
b) The duration during which the variation of number of moles O2 takes place in part (a) is 100s. Calculate the average rate of disappearance of O2 during this interval of time. Deduce the rate disappearance of NO during the same interval of time.
DO WE USE ICE TABLE IN PART B???
You don't need ice.
if you lost 5 mol O2, you used 10 mole NO2 in the same time, and you made 10 mole of NO2
avg rate O2=5/100 mol/sec
avg rate NO= twice that
