Consider the reaction: so2cl2(g)⇌so2(g)+cl2(g) kp=2.91×103 at 298 k in a reaction at equilibrium, the partial pressure of so2 is 0.156 atm and that of cl2 is 0.370 atm . part a what is the partial pressure of so2cl2 in this mixture?

1.98 x 10⁻⁵ atm.

Explanation:

∵ Kp = (PSO₂)(PCl₂)/(PSO₂Cl₂).

PSO₂ = 0.156 atm, PCl₂ = 0.370 atm.

∴ 2.91 x 10³ = (0.156 atm)(0.370 atm)/(PSO₂Cl₂)

∴ (PSO₂Cl₂) = (0.156 atm)(0.370 atm)/(2.91 x 10³) = 1.98 x 10⁻⁵ atm.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
