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:
[tex]k= \frac{ [C]^{c}*[D]^{d} }{[A]^{a}*[B]^{b}} [/tex]
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!
