A tablespoon of baking powder is added to 300g of water in a sturdy bottle and the lid is sealed tightly. The reaction of baking powder produces CO2. The reaction is endothermic.

3 NaHCO3 + NaAl(SO4)2 → Al(OH)3 + 2 Na2SO4 + 3 CO2

What are 2 things you can do to produce more carbon dioxide? You can add any chemical to the bottle, increase or decrease the pressure in the bottle, or increase or decrease the temperature.

1. Increase the temperature: By raising the temperature of the water and baking powder mixture, you can increase the reaction rate and produce more carbon dioxide. This is because higher temperatures provide more energy to the reactant particles, resulting in more collisions and a faster reaction.

2. Add an acid: Adding an acid, such as vinegar (acetic acid), to the mixture can increase the production of carbon dioxide. The acid will react with the baking powder to produce more CO2 gas. This is because the acid will provide additional reactant particles for the reaction to occur, leading to more CO2 being produced.
