Question

Indicate which conditions would keep the soda fizzy (more H₂CO₃) by selecting the correct change in the stressor from the drop down menu.

Pressure: Increase / Decrease

Volume: Increase / Decrease

Amount of CO₂ :Increase / Decrease

Temperature: Increase / Decrease

Answer 1

The reaction we are concerned with is ...

H₂CO₃(aq) ==> H₂O(l) + CO₂(g)

According to LeChatelier, to push the equilibrium to the left (more H₂CO₃), you would...

Increase the pressure (fewer moles of gas on the left)

Decrease the volume (same effect as increasing pressure)

Increase the amount of CO₂ (increase in product shifts reaction toward reactant)

Decrease the temperature (lower temp means greater solubility of CO₂ which pushes rxn to left)
