How will more carbon dioxide affect the rate of photosynthesis?

Does changing the particle size of alka seltzer tablets affect how much carbon dioxide is produced?

• I know that changing the particle size (Grinding alka seltzer into powder) speeds up the chemical reaction rate, but does it affect how much carbon dioxide is made?

• Answer:

  no, the quantity will depend on how much of the stuff you put into the mixture. You can't create or destroy stuff. If the reaction keeps up on it's own, it will go 'til it's done, however long that takes, making all of the "stuff".
