Svante Arrhenius as a prophet global warming
8 pages (2000 words)

Back in 1896, Svante Arrhenius, the Swedish climate scientist, published an article in the journal Philosophical Transactions. The scientist argued that doubling of carbon dioxide concentration in the atmosphere would lead to increase of the global surface temperature by approximately 9F (Arrhenius, 1896).… Starting from the early 1980s, a number of scientists…

1. The strength of the acid depends on the Ka values of the acid. Acids with more stable conjugate bases have higher strength. So the order of the acidic strength would be H2SO4 > HClO3 > HClO2 > H2S > H2O 4. The value of the equilibrium constant is only dependent on the temperature of the reaction.… 6. A conjugate acid base pair are the compounds formed by…

c. When is equilibrium reached in the above reaction Equilibrium is reached in the above reaction when the rate of the forward reaction is equal to the rate of the backward reaction. At equilibrium, [CaO(s)] [CO2(g)] / [CaCO3] = k' / k" = K. e. The overall rate of the forward reaction was calculated by measuring the mass of CaCO3 consumed found 1g/min.…

The Green House Gases (GHG) Effect is one of the better understood features of the atmosphere; the science having been established in the 1800's by the likes of Arrhenius, Fourier & Tyndall. Arrhenius (1896) estimated that a doubling of CO2 would cause 4.9-6.1o C increase in continental surface air temperature depending upon latitude and season, which is at the upper end of current predictions (1.4oC-5.8oC) under the third AR).…
