The sum of all CO2 emissions from 1850 to 2010, from fossil fuel emissions is equal to the total area under the graph from Problem 6-33.
a. Based on this method, how much CO2 was emitted from fossil fuels between 1850 and 2010? b. How does this compare to the atmospheric increase in CO2 between 1850 and 2010, based on measurements of CO2 in ppm in the atmosphere between 1850 and 2010? What will be an ideal response?
Estimate the system pressure and vapor phase composition for an equimolar binary mixture at 303.15 K if the vapor pressure of the pure components at 303.15 K are as follows, Psat (1) = 90 kPa; Psat (2) = 110 kPa. The activity coefficient for component (1) at this composition is 1.3 while the activity coefficient for component (2) at this composition is 1.1.
