Q and K Graph Explanation

Postby Vana Mirzakhani 3I » Thu Jan 17, 2019 11:13 pm

Does anyone remember the Q and K bar graph Dr. Lavelle explained in his slides? May someone please explain the bar graph and its patterns. Thank you.

I don't remember a bar graph relating Q and K. However, just keep in mind that if Q<K, the products are still being produced at the cost of the reactants in the forward reaction. and if Q>K, the products are still being used to create the reactants in the reverse reaction.
The only bar graph that I can recall is one relating Ka and Kb, in which when Ka increases, Kb has to decrease in order to keep Kw (1.0 x 10^-14) constant, and vice versa.

I know what graph you are talking about, and hopefully this one can help explain Q and K with respect to equilibrium.
