Reactions with more than three reactants and products

[ana-tuba]

We are trying to add the follow reaction to a mechanism file:
2C4H6 + 7O2 = 8CO + 6H2O

Since Mutation++ only allows a maximum of three reactants and products, is anyone aware of a work around for this issue? Thanks.

Hi @ana-tuba, this reaction is a composite of several others most likely because it is highly improbable that 14 molecules collide at once. This is a typical mechanism reduction technique in order to reduce the size of the mechanism but as you said, Mutation++ does not support this at this time. You could try to figure out what the elementary reactions are that lead to this global reaction, and include those instead.
