Solution: It is estimated that the net amount of carbon dioxide fixed by photosynthesis on the landmass of the Earth is 5.5 x 1016 g of CO2. All this carbon is converted into glucose.Calculate the average rate

Problem

It is estimated that the net amount of carbon dioxide fixed by photosynthesis on the landmass of the Earth is 5.5 x 1016 g of CO2. All this carbon is converted into glucose.

Calculate the average rate of conversion of solar energy into plant energy in MW (1W = 1J/s). A large nuclear power plant produces about 103 kJ. The energy of how many such nuclear power plants is equivalent to the solar energy conversion?

12 CO2(g) + 11 H2O(l) → C12H22O11 + 12O2(g), ΔH = 5645kJ
