The decomposition of N2O5 takes place in carbon tetrachloride at room temperature according to the equation, 2 N2O5 (soln) → 2 N2O4 (soln) + O2 (g). The rate constant is 2.35 x 10−4 s−1 at 293.0 K and 9.15 x 10−4 s−1 at 303.0 K. Calculate Ea for this reaction.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
