Write the balanced equation for the preparation of elemental born by reduction with dihydrogen
Answers
Answer:
The Bosch reaction is a chemical reaction between carbon dioxide and hydrogen that produces elemental carbon (graphite), water, and a 10% return of invested heat. It is named after the German chemist Carl Bosch.[citation needed] This reaction requires the introduction of iron as a catalyst and requires a temperature level of 530-730 degrees Celsius.[1]
The overall reaction is as follows:
CO2(g) + 2 H2(g) → C(s) + 2 H2O(g)
The above reaction is actually the result of two reactions. The first reaction, the reverse water gas shift reaction, is a fast one:
CO2 + H2 → CO + H2O
The second reaction is the rate determining step:
CO + H2 → C + H2O
The overall reaction produces 2.3×103 joules for every gram of carbon dioxide reacted at 650 °C. Reaction temperatures are in the range of 450 to 600 °C.
The reaction can be accelerated in the presence of an iron, cobalt or nickel catalyst. Ruthenium also serves to speed up the reaction.
