Question

2. The reaction Co(H2O)2 + 4HCI + heat --- --> CoCl2 + 6H2O + 4H+1 18 an endothermic reaction. How will each of the following changes affect the equilibrium concentrations, i.e., will the reaction shift right or left? Does this agree with what you have observed in the experiment? a. adding HCl to the solution b. cooling the solution c. adding heat to the solution d. adding water to the solution

Answer 1

Answer

To answer this question we need to understand Le Chatliers principle according to which a system in equilibrium tends to remain in the equilibrium which means that the equilibrium tries to nullify any change that is done to disturb the equilibrium.

for the reaction 2 Colthol + 4HU t heat Codly Coco u2 + 6H0 + 4H+ on adding concentration of shifts in such of He decreases Hee (reactant) to the solu reactant increases. The reaction a way that the concentration ie. lawards right direction. On cooling the the direction towards left. solution , reaction where temperature shifts in increases ie. on adding heat to the solution, reaction shifts in the direction where temperature is low ie towards right, shifts on shith ie adding in In the water to the the direction left direction. solution, where tho reaction gets consumed
