Step 1

The given reaction is:

Cu (s) + 2AgNO3 (aq) ═ Cu(NO3)2 (aq) + 2Ag (s)

 

According to Le Chatelier’s principle states that on increasing the temperature of an exothermic reaction, the rate of backward reaction increases because the backward reaction of an exothermic reaction is endothermic and its rate increases with an increase in temperature.

 

As the given reaction is exothermic, therefore, an increase in temperature will not increase the rate of reaction.

Step 2

The increase in pressure of the system does not affect the rate of liquid and solid phase reaction.

 

As the given reaction does not consist of any gaseous species, therefore, the increase in pressure of the system will have no effect on the rate of reaction.

Step 3

Le Chatelier’s principle states that the increase in concentration of reactant molecule increases the rate of forward reaction which leads to the formation of a greater number of product molecul...
