How Is the Equilibrium Formula Derived?

[Haftred]

In my general chemistry class, my professor proved the equilibrium formula:

K_eq = ([C]^c[D]^d)/([A]^ab)

However, I lost my notes ; hopefully someone can help derive it for me. Thanks.

Have you tried looking in your book?

it's not proved in my book

Write Law of mass action for forward and backward rxn

At equilibrium rate of forward rxn= rate of backward rxn
And K_{eq} = \frac{k_f}{k_b}

Where k_f & k_b represent the rate constant for fwd & bkw rxn
