Answer to Question #57580 in Chemistry for Emma

Question

Describe three uses of rhodium as a catalyst (include both a written description and the balanced chemical equation)

Answer 1

Rhodium catalysts are used in red-ox processes such as for example:
hydrogenation reaction of unsaturated hydrocarbons, when molecule of hydrogen is appends to the double or triple bounds of hydrocarbon:
H_2 C=CH_2+H_2→H_3 C-CH_3
Vapor conversion of carbon oxide. Water is reduced to hydrogen by the carbon dioxide:
CO+H_2 O→〖CO〗_2+H_2
Carbonylation reaction – adding the carbon dioxide molecula itno organic substance, such as methanol:
H_3 COH+CO→H_3 CCOOH
