2SO3(g) -> 2SO2(g)+O2(g)
Calculate Keq for this reaction if the equalibrium concentrations are: |SO2|=0.42M; |O2|=0.21M; |SO3|=0.072M

The equilibrium constant for the reaction comes out to be 7.145

Explanation:

Given concentration of all the species at equilibrium are shown below

\\

Given reaction is shown below

for the reaction is 7.145

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
