Which of the following statements is not true?
1.Chemical equilibria are examples of reversible processes.
2.When multiple reaction steps are in equilibrium, then the equilibrium constant for the net reaction is the product of the individual reactions.
3.The equilibrium constants are unitless (according to the book).
4. The value of Keq for the forward reaction equals 1-Keq for the reverse reaction.

#4 is not true; the others are true. I why #3 has that "according to the book". There are many posts I see and even a few texts that claim to show units for Keq, Ksp, Kc, Kp. etc. but in fact according to the book or not there are no units for these constants. The reason there are no units is because activities go there for concentrations and activities have no units. For #4, the correct statement is that the value of Keq for the forward reaction equals 1/keq for the reverse reaction.
