Question

Based on the equilibrium constants given, in which of these reactions are the products most favored over the reactants? a) Keq = 0.002 b) Keq = 0.0 c) Keq = 3.5 d) Keq = 6.0 ×10^-4

Answer 1

For the equilibrium constant we have the following equation:

$A+B\rightarrow C+D$

$K_{eq}=\frac{\lbrack C\rbrack^c\lbrack D\rbrack^d}{\lbrack A\rbrack^a\lbrack B\rbrack^b}$

So, we have the products above and the equilibrium constant is directly proportional to the concentration of products. Therefore, if we want to obtain a higher concentration of products, we must look for the highest value of the constant.

In this case it will be 3.5, so the answer is c)Keq 3.5
