The world burns around 9.0 x 10 12 kg of fossil fuel per year. Utilizes the combustion of octane as the representative reaction and find out the mass of carbon dioxide (the most significant greenhouse gas formed per year by this combustion. Define the current concentration of carbon dioxide in the atmosphere is approximately 387ppm by volume.
By what percentage does the concentration raise in one year due to fossil fuel combustion? Estimate the average properties of the complete atmosphere by assuming that the atmosphere extends from sea level to 15 km as well as that it has an average pressure of 381torr and average temperature of 275 K . Presume Earth is a perfect sphere with a radius of 6371 km.
Explain by what percentage does the concentration increase in one year due to fossil fuel combustion?
