Default surface reaction rate plot at diffusiion limit cas

I have a diffusion-limited case for surface reaction. So the reactant at surface is almost zero, and reaction rate is limited by the diffusion from bulk face, which is achieved by using a high pre-exponent factor value (1e15). The simulation shows that the gas products formed at solid surface diffused back into gas phase by plotting the contour of species, but when plotting x-y reaction rate on the surface, the rate is zero, any comments?

Thanks

Have you tried looking at countours and/or ticking the node option?? I mean contours of the surface.

It may be a bug.

The reaction rate will have to be non-zero.
