An air purifiction system involving litium hydroxide, LiOH, was used. LiOH absorbs carbon dioxide.

2LiOH(s) + CO2(g) <---> Li2CO3(s) + H2O(l)

Use Le Chatelier's principle to explain why the amount of time astronauts can spend in a space-craft is limited?

This is what I think. When we breath in oxygenm we breath out carbon dioxide. The carbon dioxide reacts with the lithium oxide and continues to produce h2o and li2co3. if they keep releasing carbondioxide, they'll keep producing li2co3 and h20. I don't exactly see whats wrong with that. Is Li3CO2 hazardous or something.
