Parameters of NaHCO3 + citric acid + H2O + NaCl mixture potentially impacting functional efficacy in pest control application?

I have been searching for infomation on this application, but have some specific questions that I have not seen directly addressed in the Google/Stack Exchange posts I've come across thus far; below are some posts I've read through):


* [Baking Soda + Citric Acid + Water = CO2, how much though? [closed]](https://chemistry.stackexchange.com/questions/34898/baking-soda-citric-acid-water-co2-how-much-though)
* [Chemical reaction to produce 5 liter of gas [closed]](https://chemistry.stackexchange.com/questions/87457/chemical-reaction-to-produce-5-liter-of-gas/87460#87460)
* [Why doesn't baking soda react with the solid form of an acid?](https://chemistry.stackexchange.com/questions/20123/why-doesnt-baking-soda-react-with-the-solid-form-of-an-acid)


I was a physics major in my school days and had to give up on chemistry due to scheduling conflicts, so I'm out of my depth here and unsure if I'm making accurate inferences from what I'm reading. I'd appreciate if someone can clarify on the two uncertainties I have below:


* Does the amount of `water` *only* affect the **rate of** reaction between `sodium bicabonate` + `citric acid`, irrespective to whatever ration the pair consist of? In other words, is it correct to assume that given static values/rations of NaHCO3 and C6H8O7, the gross volume of CO2 produced will remain the same regardless of dilution, given sufficient time and assuming the inputs thoroughly undergo the reaction?
* Does `sodium chloride` interact with the reaction in any meaningful manner? As this will be one of the two mechanisms for lethality, I want to make certain that misuse (over applying, etc.) will not impact the functional efficacy of the CO2 production.


Thank you!
