Question

Explain the point of the following demonstration incorporating at least the following words: kinetic energy, entropy, rate of reaction, lesser or greater amount of time for the reaction to take place, increase/decrease, collisions, possibilities. Zinc pellets (chunky) were added to cold 1M hydrochloric acid and separately to hot 1 M hydrochloric acid. First write the correctly balanced equation between line and hydrochloric acid, followed by the explanation. Consider the following reaction: Energy + (Co(H_2O)_6]^2+ (aq) (pink) + 4CI (aq) |CoCl_4]^2(aq) (blue) + 6H_2O(l) Name of B? Silver nitrate solution (Formula ?) was added to the reaction. What was observed when the silver nitrate was added to the reaction? Explain the observations using le Chatelier's principle making sure to justify your observations. Write the complete equation for the compound that was formed when the silver nitrate solution was added. Separately the temperature of the equilibrium system was lowered. The initial color of the equilibrium system is light purple. When the temperature is lowered, use Le Chatelier's principle to state and explain the effect on the direction of equilibrium What will be the color of the reaction after the change?

Explanation / Answer

balanced equation:

Zn + 2HCl ----------------------> ZnCl2 + H2

explanation: in cold condition the rate of reactivity is less. but in hot condition the rate of reaction is high that means the leberation of hydrogen gas will be fastet in case of hot condition

A ----------------> hexaaquacobalt(II)ion

B------------------> tetrachlorocuprate (II)

a) AgNO3 silver nitrate solution

b) when silver nitrate added to the solution the formation of product decreases due to formation of white precipitate with Cl-

c) according to lechatliers principle on removal of any reactant conentration the reaction shifts to reactant side

d) complete equation:

AgNO3 + Cl- --------------------> AgCl (s) + NO3-
