C.)If 588 mlol of Al2O3 reacts with unlimited H2SO4, how many moles of each of the products will be produced ? With the Ni-Co/Al2O3 catalyst, the H2/CO molar ratio was increased from 0.74 (no steam) to 0.94 (CO2:steam ratio; 4:1) however the H2/CO molar ratio decreased with further steam addition. The molar ratio plots of n(N2+H2)/n(N2H4) versus time for the recycling test of hydrous hydrazine decomposition over NiPt0.057/Al2O3 catalyst at 30°C. It should be noted that the chemical resistance of Al2O3 to concentrated and/or dilute acids, alkalis, halogens and metals is quite good.
