NettetGold is reactive, just not very reactive relative to other metals. It sits very low in the reactivity series with platinum and other ‘noble metals’. All the noble metals (an … NettetThe fact that the absorbed hydrogen is extremely reactive suggests that it is present either as atomic hydrogen or as a very reactive platinum hydrogen compound or complex. In finely divided form platinum is an excellent catalyst; about half of the annual production of the metal serves this purpose, most of it in the petrochemical industry.

NettetPlatinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. NettetThe interpretation must be that the reactive oxygen is adsorbed only weakly or not at all, and that vacant sites (progressively filled at higher hydrogen pressures) are required for reaction. The linear pressure-time curve could result from the opposite signs of the reaction orders, but this cannot be so at hydrogen pressures below about 1 cm and some …
