In summary, the conversation discusses the concept of "kinetically favoured" in a chemical reaction. The speaker suggests breaking down the word to understand its meaning, and explains that it is not a rigidly defined term like a law or unit. It is used to describe a reaction that may produce multiple products, with one being more stable (thermodynamically favoured) but the other being produced faster in certain conditions (kinetically favoured).

I had my chem lab, and I know that kinetically favoured is realted to fast reaction and so forth, but I can't just define kinetically favoured. Please help me?

The easiest thing to do would be to break down the word itself. If something is favored what does it mean? If something is kinetic what does it mean? Then, combine the two definitions.

I don't think it is rigidly laid down like a law, unit or other definition you have to learn. It just means what it suggests. Particularly contrasted to 'thermodynamically favoured'. E.g. given reactants often produce more than one product. One product might be more stable than another, i.e. thermodynamically favoured, but the path to another might in given conditions be faster so that is what you could get more of and you would call that being kinetically favoured.
 

FAQ: What does kinetically favoured mean?

What does it mean for a reaction to be kinetically favoured?

When a reaction is kinetically favoured, it means that it occurs at a faster rate compared to other potential reactions. This is often due to a lower activation energy, making it easier for the reaction to occur.

How is kinetic favourability different from thermodynamic favourability?

Kinetic favourability refers to the speed at which a reaction occurs, while thermodynamic favourability refers to the overall energy change of a reaction. A reaction can be kinetically favoured but not thermodynamically favoured, meaning it occurs quickly but has an unfavorable energy change.

Can a reaction be both kinetically and thermodynamically favoured?

Yes, a reaction can be both kinetically and thermodynamically favoured. This means that it occurs quickly and has a favorable energy change, making it both fast and energetically favorable.

What factors contribute to a reaction being kinetically favoured?

There are several factors that can contribute to a reaction being kinetically favoured, such as a lower activation energy, a higher concentration of reactants, and the presence of a catalyst. These factors make it easier and faster for the reaction to occur.

How does temperature affect kinetic favourability?

Generally, an increase in temperature leads to an increase in kinetic favourability. This is because higher temperatures provide more energy for molecules to overcome the activation energy barrier, allowing the reaction to occur at a faster rate. However, this may not always be the case and can depend on the specific reaction and its reactants.
