Answer:
Removing O₂, means removing one of the reactants and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
Explanation:
The principle that explains how changes in temperature, Concentration and Pressure of reactants or products of a reaction at equilibrium affect the equilibrium position of the reaction is the Le Chatelier's principle.
The Principle explains that a system/process if a system/process which is at equilibrium is disturbed/perturbed/constrained by one or more changes (in concentration, pressure or temperature), the system would shift the equilibrium position to counteract the effects of this change.
Removing O₂, means removing one of the reactants (changing its concentration) and the system would counteract this effect by producing more O₂, thereby shifting the equilibrium position to the left and favouring the backward reaction.
Answer:
Electrophilic aromatic substitution is the reaction in which the bromobenzene is present with the presence of the nitronium ions and results in the formation of para-bromonitrobenzene.
Explanation:
Bromobenzene in the presence of nitronium ions preferntially forms para-bromonitrobenzene rather than meta or the ortho product.
so. here the reaction been mentioned refers to Electrophilic aromatic substitution.
Electrophilic aromatic substitution: An organic reaction is referred as the aromatic substitution.
In this type of organic reaction a system is present which is an organic system to which an atom gets attached which get replaced by an electrophile.
It is one of the most important reactions of the field synthetic organic chemistry.
the usage of these reactions are in synthesis of the most important intermediates which are used as the precursors in agrochemical, industrial and pharmaceutical products.
