in the reaction below how would adding more of product C affect the equilibrium of the system? A+B arrows both ways C+D

In the endothermic reaction below how would adding hear affect the equilibrium of the system? A+B + energy arrows both ways +D

In the following reaction, if you wanted to produce more hydrochloric acid (HCl2), what would you do? 4HCl + O2 arrows both ways 2H2O + Cl2

Respuesta :

Answer:

First answer : equilibrium shift towards the formation of the reactants

Second answer :  equilibrium shift towards the formation of products

Third answer : need to add more H2O.

Explanation:

  • In a reversible chemical reaction, the shift of equilibrium of the reaction towards the production of products or reactants is dependent on the abundance of reactants or products.
  • As in the first question, if the products available are more (C) than the reactants, then the equilibrium of the reaction would shift towards the formation of the reactants (A and B).
  • As in second question, If reactants available are more (heat addition) than that of products, then the equilibrium of the reaction would shift towards the formation of products (D).
  • As in the third question, we want to generate more HCL, which is the reactant, so we need to increase the amount of product, so we need to add more H2O.
