I suppose that the reaction is defined according to the image below. If not, where do I enter it?

I see that the VR_RATE version was not complete (I was trying to change the coefficients to see if each part was taken into account). Below is the correct version.


With this reaction rate, a kinetic rate of reaction is calculated (see below) but no hco3 is produced, same for h+. 




Do you see any error or oversight in the way this is implemented?
