Help with the species conservation equation

Hi guys.
I came accros this mass conservation equation (where diffusion is neglected) but I don't know what the terms are ....please take a look and see if you can figure those units out (see the picture)

As you can see, this is an ODE equation, it is assumed a zeroth-dimensional model. Therefore classical terms as convective and diffusive fluxes do not appear.

Thanks FMD Denaro...but what are the W and omega ??
