(a)
Interpretation:
The effect of decrease in the container volume for the given amounts of reactants and products has to be predicted.
Concept Introduction:
Le Chatelier’s principle:
Le Chatelier’s principle states that the changes in the temperature, pressure, volume and concentration of the system results in the change in system to attain new equilibrium. It is used to understand the conditions of a reaction which favours increased product formation.
Change in equilibrium due to pressure changes:
On increase in the system pressure, the equilibrium shifts towards fewer moles of gas, because, for gases,
On decrease in the system pressure, the equilibrium shifts towards more moles of gas, because, for gases,

- A. Determine the number of electrons in a system of cyclic conjugation (zero if no cyclic conjugation). B. Specify whether the species is "a"-aromatic, "aa"-anti-aromatic, or "na"-non-aromatic (neither aromatic nor anti-aromatic). (Presume rings to be planar unless structure obviously prevents planarity. If there is more than one conjugated ring, count electrons in the largest.) 1. A.Electrons in a cyclic conjugated system. 18 B.The compound is (a, aa, or na) a 2.
