Hi,

Can anyone please provide help for this problem.

What are appropriate predefined macros for the following:

1. An injected dpm particle with an initial surface site density needs to follow the following reaction:
Cs-H + H => Cs-* + H2
Initial site surface density of particle is Cs-H (The will be predefined in kmol/m2).
H and H2 are from the continuous phase.
Site density of particle after reaction will include Cs-*.

2. A surface reaction which includes deposition on the particle.
Cs-* + C2H2 => Cs-H + H2 + 2C
2C are the deposited carbon and should have a site density of Cs-*
How can I update the particle size after the deposition?

Note that the initially injected particles were based on the nucleation rate of a reaction in the continuous phase.

Thanks
