Answer:
At equilibrium the rate of the forward reaction is equal to the rate of the backward reaction.
When the product of a reaction at equilibrium is increased the equilibrium will shift left or to the reactant side. As a result the excess product will get converted to reactant. This is in accordance to Le Chatelier's principle.
Le Chatelier's principle states that when a system is subjected to stress the equilibrium will shift in a direction to minimize effect of the stress.
Thus the products added to the system at equilibrium will make the equilibrium shift to the reactant side, the rate of the reverse or backward reaction will increase.

Answer:tetrahedral
Explanation:
According to Valence Shell Electron Pair Repulsion Theory (VSEPR). The number of electron pairs on the valence shell of the central atom in a molecule influences the shape of that molecule. Four electron pairs around the central atom of a molecule leads to a tetrahedral geometry as predicted by VSEPR.
The decomposition of the given compound, Pb(NO3)2, will yield 3 different simpler compounds which are lead oxide (PbO), nitrogen dioxide (NO2), and oxygen (O2). Based on the given chemical formula, the ionic component of the compound are Pb²⁺ and 2 ions of NO₃²⁻.
The phases of these compounds will have to be solid and aqueous.
