Areaction goes essentially to completion. would you expect the value of k to be large or small?

Hello!

The value of K will be large.

K is the value of the equilibrium constant of a reaction. If we have a chemical reaction in the following way:

aA+bB⇄cC+dD

The K value will be:



From this equation, we can see that as the concentration of the products is larger, the k value will also be larger, and as the concentration of the reagents is lower, the k value will be larger. That means that for a reaction which goes to completion (i.e. the concentration of the products is large and the concentration of reagents is low), the k value will be very large.

Have a nice day!
