(a)
Interpretation:
A balanced
Concept introduction:
Balanced Chemical equation:
A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.
(b)
Interpretation:
The number of AB molecules increase, decrease or remain same when the volume of the equilibrium mixture is decreased has to be explained.
Concept introduction:
Le Chatelier's principle states that if a system in equilibrium gets disturbed due to modification of concentration, temperature, volume, and pressure, then it reset to counteract the effect of disturbance.
Effect of change in pressure:
- According to Le Chatelier's principle, increase in pressure (decrease in volume) leads to flow of reaction in direction where number of moles is less.
- According to Le Chatelier's principle, decrease in pressure (increase in volume) leads to flow of reaction in direction where number of moles is more.

- In the decomposition reaction in solution B → C, only species C absorbs UV radiation, but neither B nor the solvent absorbs. If we call At the absorbance measured at any time, A0 the absorbance at the beginning of the reaction, and A∞ the absorbance at the end of the reaction, which of the expressions is valid? We assume that Beer's law is fulfilled.arrow_forward> You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: 1. ☑ CI 2.
