Use the reactions below and their equilibrium constants to predict the equilibrium constant for the reaction, 2A(s) <-> 3D(g).
2A(s) <-> 1/2B(g) + C(g) K1 = 0.0334
3D(g) <-> B(g) + 2C(g) K2 = 2.35
what is the reaction order? If the unit is M^-1 s^-1, what is the reaction order? Use the rate laws to determine the unit for the rate constant.
The relationship (if any) of the lattice energy of compounds such as ZnO vs. H3BO3 vs. their respective solubilities. For instance, at neutral pH and standard conditions
