the first step in the ostwald process$($ used to produce nitric acid $)$ is the formation of nitric oxide from ammonia and oixygen $4$NH$3($g$)+5$O$2($g$)=4$NO$($g$)+6$H$2$O$($g$.$ if the feed going to the reactor contains $0\mathrm{.}330$ mol NH$3/$mol O$2.$ what the limiting reactant and the percent excess of the other reactant and what mass flow rate of NH$3$ in lbm$/$h is required to produce $2130$lbm of NO per day
