Calcium oxide is used to remove pollutant so2 from smokestack gases. the δg° of the overall reaction is -418.6 kj. what is pso2 in equilibrium with air (po2 = 0.21 atm) and solid cao?

cao(s)+so2 (g)+1⁄2o2 (g)⇔caso4 (s)

Gibbs free energy is defined as the combination of entropies and enthalpies into a single value.

The for the given reaction is atm.

The Gibbs free energy is calculated as the sum of enthalpy product's temperature and entropy of the system.

Formula =

Where,

R = 8.314, T = 298, and K =

Thus, the value of for the given reaction is atm.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
