Summing reactions/rate constants

[Sosi]

Hi!

I have a couple of reactions whose rate constants are known:

A + B -> C + D (reaction 1)
C + B -> E + F (reaction 2)

and I want to know the rate constants of the sum of these reactions. That is:

A + 2B -> D + E + F (reaction 3)

How may I know the rate constant for reaction 3, assuming that I know the rate constants for reaction 1 and 2?

Thanks for all the help!

You need to provide some additional information about the lability of the reactions (1 and 2) before you can proceed.

all the species from reactions 1 and 2 are stable. I was advised to consider an open system in which the reactions were not reversible. Does this help? I'm not seeing how I can use this information...

Thanks!
