Which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of ni2+ is increased? view available hint(s) which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of is increased? ni(oh)2(s)⇌ni2+(aq)+2oh−(aq) [ni(h2o)6]2+(aq)+3en(aq)⇌[ni(en)3]2 +(aq)+6nh3(aq) ni2+(aq)+6nh3(aq)⇌[ni(nh3)6]2+ nis(s)⇌ni2+(aq)+s2−(aq)

Explanation:

According to Le Chatelier's principle, any disturbance occurring in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.

As the given reactions are as follows.

When concentration of is increased in this reaction then reaction will shift in a direction that will be opposing the change. This means that the reaction will shift in backward direction.

In this reaction, both water and ethylenediamine are neutral molecules. Hence, charge on nickel on each side will be equal to +2. Therefore, reaction will remain in equilibrium.

When we increase the concentration of then equilibrium reaction will shift in the forward direction.

Here, on increasing the concentration of will shift the equilibrium in backward direction.

Thus, we can conclude that out of the given options is the chemical reaction in which equilibrium reaction will experience a shift towards the products in equilibrium position when the concentration of is increased.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

i think   the answer is c hope i'm right
