Brainliest fast! which of the following is an example of a unimolecular reaction? a: n2o4(g) > 2no2(g) b: o + ch4 > oh + ch3 c: 2no(g) + o2 > 2no2(g) d: co(g) + no3(g) > no2(g) + co2(g)

A unimolecular reaction occurs when a molecule rearranges itself to produce one or more products. An example of this is radioactive decay, in which particles are emitted from an atom. Other examples include cis-trans isomerization, thermal decomposition, ring opening, and racemization. 

So my answer is C

The correct answer is A
