When the k ep value is large, the number representing [a] [b] must then the number representing [c] [d]?

Consider the equilibrium,

So the denominator [A][B] must be smaller than the numerator [C][D] for the equilibrium constant value, to be large.

This shows that the equilibrium is favored towards the products.

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
