Question

What happens when methane reacts with conc. \[HN{{O}_{3}}\] at high temperature?
a.) Nitromethane is formed
b.) Methanol is formed
c.) \[C{{O}_{2}}\]and \[{{H}_{2}}O\] are formed
d.) \[CO\]and \[{{H}_{2}}O\] are formed

Answer 1

Hint: The more the atoms move, the more collisions occur, and the more reactions occur between the chemical = faster reaction rate. Increasing the temperature will cause chemical reaction to occur faster. Decreasing the temperature, causes the particles to lose energy which causes them to move around less and slower.
The correct answer is A.
\[C{{H}_{4}}+HN{{O}_{3}}\xrightarrow[{{400}^{0}}C]{\Delta }C{{H}_{3}}N{{O}_{2}}+{{H}_{2}}O\]

 Complete answer:
Here in the reaction we get nitromethane also the formation of\[{{H}_ {2}} O\] takes place but no \[CO\]and methanol takes place.
Nitromethane, now and then abbreviated to simply Nitro, is a natural compound with the synthetic equation \[C{{H}_{3}}N{{O}_{2}}\]. It is the least difficult natural nitro compound. It is a polar fluid usually utilized as a dissolvable in an assortment of modern applications, for example, in extractions, as a response medium, and as a cleaning dissolvable. As a middle of the road in natural amalgamation, it is utilized broadly in the production of pharmaceuticals, pesticides, explosives, strands, and coatings.
Nitromethane is utilized as a fuel added substance in different motorsports and pastimes, for example Top Fuel racing and smaller than usual inward ignition motors in radio control, control line and free flight model aircraft. Nitromethane is created modernly by consolidating propane and nitric acid in the gas stage at 350–450 °C (662–842 °F).
This exothermic response creates the four mechanically huge nitroalkanes: nitromethane, nitroethane, 1-nitropropane, and 2-nitropropane. The response includes free radicals, including the alkoxyl radicals of the sort \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}O\], which emerge by means of hemolysis of the relating nitrite ester. These alkoxy radicals are helpless to discontinuity responses, which clarifies the arrangement of a blend of products.

Note: The chief utilization of nitromethane is as a stabilizer for chlorinated solvents, which are utilized in cleaning, semiconductor preparing, and degreasing. It is likewise utilized most viably as a dissolvable or dissolving specialist for acrylate monomers, for example, cyanoacrylates (all the more usually known as "super-pastes").
