 So, this is the starting configuration, this energy around minus 100, and we see that if we go here, this concerted motion, the barrier goes up to zero, so it's 100 kilojoules per mole, and the start of it has two water molecules adjacent to the CO2 within the van der Waals distance, and now what I'm doing is I'm forming that bond and forcing this bond to form, and forcing that bond to form, and as you can see what's happened is that it's ejected this H2O and formed carbonic acid.
