LO 6.25….AGAIN!
Having looked at the "thermal energy" nonsense in LO 6.25 for around 5 years, and having written this blog post in Feb 2016, and this blog post in...
All creatures great and small and 2016, 6
All things bright & beautiful, all creatures great and small. Remember that hymn? We often talk about remembering the little things, well here's...
Another ∆G° mystery
We've lived through the nonsense of the inclusion of PES in the new AP Chemistry curriculum. Many think the exclusion of quantum numbers, stinks....
Writing good answers to AP Equilibrium problems
Here's the latest in the 'writing good answers' series, Writing good answers to AP Equilibrium problems. This post only deals with aspects of...
Le Châtelier’s principle in action
Following the mention of the cobalt(II) complex ion system in this post from a couple of days ago, here's a 30 second video clip of Le Châtelier's...
Water in equilibrium mixtures and Le Châtelier’s principle
When it comes to water in equilibrium mixtures and Le Châtelier's principle, things can be confusing, so let's try to take some of the mystery out...
∆G and ∆G° revisited
∆G and ∆G° can be tricky things. This is partly evidenced by a post that I wrote back in January of 2012 continuing to be one of the most popular of...
‘Expanded LCP’ or ‘Q versus K’ explanations?
It's never been OK, on the AP exam, to offer a simple, 'because of Le Châtelier’s principle' argument as the explanation for the shift of an...
Inert gases and gaseous equilibrium mixtures
What happens when an inert gas is added to a gaseous equilibrium mixture at constant volume? Before we answer that question, it might be worth...
