Explain giving reasons "The presence of CO reduces the amount of haemoglobin available in the blood for carrying oxygen to the body cells".

Construct a reaction between carboxy haemoglobin with oxygen from the following equations. Haemoglobin +O_2 (aq) rarr Oxyhaemoglobin, Delta H_(l)=-23.1 kJ / mol rarr(1) Haemoglobin +CO (aq) rarr Carboxyhaemoglobin, Delta H_(2)=,-32.4 kJ / mol rarr(2) a. Using the value of Delta from your equation, account for the extreme toxicity of carbon monoxide. b. What are the sources of carbon monoxide in the atmosphere. How can you rectify the adverse éffects of C O in atmosphere?
