`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?.

Options

A. `CO` forms complex with haemoglobnin
B. `CO` has low soluility in `H_2O`
C. `CO` has high activation enrgy
D. `CO` is toxic in nature

Answer

C
