What is the total number of pairs of electrons shared in a molecule of n2?
(1) one pair (3) three pairs
(2) two pairs (4) four pairs

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

im not exactly sure but i think its b!
