Consider the following reaction in chemical equilibrium: 2brno(g)⇌2no(g)+br2(g) what is the effect of adding additional br2(g) to the reaction mixture? what is the effect of adding additional brno? match the words in the left column to the appropriate blanks in the sentences on the right. make certain each sentence is complete before submitting your answer.

The reaction would shift to the left on adding Br2(g)

             The reaction would shift to right on adding BrNO(g)

Explanation:

The concept can be explained on the basis of LeChateliers principle.

LeChateliers principle explain the effect on equilibrium when a reaction system at equilibrium is subjected to any disturbance or change in conditions then the reaction shifts in such a way so as to reduce the effect of that change or disturbance and again establish the equilibrium.

For example if we add more reactants in a given reaction at equilibrium, the reaction would shift in such a way so that it can reduce the effect of increasing the concentration of reactants and hence the reaction would favor that direction in which it can reduce the concentration of reactants.So when we increase the concentration of reactants  the reaction would move towards the formation of more products and so the concentration of reactants would be less in the reaction.

Likewise if we increase the concentration of products so the reaction would shift in such a way so that it can oppose the increased concentration of products so the reaction moves towards more formation of reactants that is the products decompose to form reactants and reaction moves backwards.

In this reaction:

2BrNO(g)⇄2NO(g)+Br₂(g)

When we add more amount of Br₂(g) the reaction would proceed in such a ways so that oppose the increased concentration of Br₂(g).Hence the reaction would move towards left that is backwards.

When we add more amount of BrNO(g)the reaction would proceed in such a ways so that oppose the increased concentration of BrNO(g).Hence the reaction would move towards right that is forward.
