Question

The sequestration of carbon dioxide is critical to reducing greenhouse emissions. Taking a lesson from planet earth, which stored carbon dioxide as alkali and alkaline earth metal carbonates over geological time scales, let's determine which alkaline earth metal oxide most stably stores carbon dioxide as a carbonate. So, consider the decomposition of group II (alkali earth) solid carbonate, i.e, solid beryllium carbonate, magnesium carbonate, calcium carbonate and barium carbonate (we’ll skip strontium carbonate) to form solid metal oxides and gaseous carbon dioxide. (A) Calculate the temperature at which the decomposition is thermodynamically favorable under standard pressure conditions. (B) Which of the group II carbonates would you pick to most stability sequester carbon dioxide?

Answer 1

A) as we all know this very well that carbon dioxide and other gases like methane are very much responsible for the emssion of green house and raised the problem of global warming in our day to day life. but on the other hand if we take the condition of the earth than it absorb the greenhouse gases in in it with the help of alkali earth metals and form the earth products in the form of carbide. this help in the reductions of the global warming and the concerntration of the emission of the further gases.

B) barium carbonate is the most stable due to lower shell numbers and due to the less reactive as it come in the light alkali metals category and thus it will be less reactive and thus form the stable form of carbonate.
