Is there a way to exclusively favor one reactant-product combination over another (ex. CO from methane only, not CO2)?

Catalysts can often provide extremely high selectivity in the production of a single product from reactive starting materials. A great deal of effort is directed at this goal in the chemical industry. I’m a bit nervous about the word “exclusively” which is an absolute like “dead” or “pregnant”. What I can tell you is that selectivities of >99.9% are often achieved.

  • If burning methane makes CO^2, is burning natgas good for the environment? No. Leaving natural gas underground is good for the environment. As soon as you bring it above ground, then the question is comparative harm. Burning it is less harmful for climate change, but more harmful for local airpollution, but both are much more harmful than leaving it underground.
  • Why is carbon tetrachloride more stable than methane? It is impossible to compare the stability of methane and carbon tetrachloride directly as the do not have a common frame of reference. At the same time you cannot claim that the dichlorine molecule is less stable than the hydrogen chloride molecule. The only true observation that you can make is th...
  • Why carbon tetrachloride is more stable than methane? When a mixture of methane and chlorine is exposed to ultraviolet light – typically sunlight – a substitution reaction occurs and the organic product is chloromethane. However, the reaction doesn't stop there, and all the hydrogens in the methane can in turn be replaced by chlorine atoms. As in th...
  • What is the main property of a gas to be a greenhouse gas? How is CO2 considered a greenhouse gas and not methane? Your premise is wrong. Methane is very much regarded as a greenhouse gas: FAQ: What is the greenhouse effect? The greenhouse effect is the way in which heat is trapped close to the surface of the Earth by “greenhouse gases.” https://climate.nasa.gov/faq/19/what-is-the-greenhouse-effect/ Its clima...
