Consider the following reaction at a certain temperature, which initially only contains SO3(g) 2SO3(g) ⇌ 2SO2(g) + O2(g)

The initial partial pressure of SO3(g) is 0.125 bar. When the reaction reaches equilibrium, the total pressure is found to be 0.164 bar. calculate K for this reaction. Express your answer to three significant figures.

Which statement best summarizes the importance of ernest rutherford’s gold foil experiment? it proved that all of john dalton’s postulates were true. it verified j. j. thomson’s work on the atomic structure. it showed that an electron circles a nucleus in a fixed-energy orbit. it showed that a nucleus occupies a small part of the whole atom.
