CO_2 and H_2 O absorbs strongly in the infrared rrgion and its presence in the atmospheere dectrases the loss fo heat form the enrth by radistiion . This global warming is called the greenhouse effect (other gases , including the oxides of nitraongen form car exhauset freons from aerosols and refrigeratirs and methane from bacteria in the soil and in the rument cows , also add to the reeenhouse effect ). The concentration fo atmospheric CO_2 has increased by 10% . The is rsulting in the increase in the mean temperature fo the earth by 2. 5^@ C , varying form 2^@ C t the equlator to 4^@ C at the poles . This could have dramatic effects on the climate. The equilibrium constant (K_(p)) for the reaction 2CO_((g))underset(larr)(rarr)2CO_(2(g)) is 1.4xx10^(90) at 25^(@)C . Given this enormous value, why does not CO convert totally into CO_(2) in the troposphere?.
