QUESTION
The total surface area of the earth consisting of forest, cultivated land, grassland and desert is 1.49x10^8 km^2.
The total surface area of the earth consisting of forest, cultivated land, grassland and desert is 1.49x10^8 km^2. Every year, the mass of carbon fixed by photosynthesis by vegetation covering this land surface according to the reaction 6CO2(g)+6H2O(l)-->C6H12O6(s)+6O2(g) is about 450. metric Tons/km^2. Calculate the annual enthalpy change resulting from photosynthetic carbon fixation over the land surface given above. Assume P=1 bar and T=298.15K.
