Question

Select the correct answer.

Answer 1

(NH4)2CO3(s) ⇄ 2NH3(g) + CO2(g) + H2O (g)

The  effect  that adding  water (H2O)   have in reaction above is  that The  concentration of the product  would  decrease, and the concentration of reactant  would increase. (answer  C)

   Explanation

•  If the  concentration   of one substance is changed, the equilibrium  shift to minimize  the effect of that change.

• H2O   in reaction above  is  a product.

• Increase of water (H2O)  concentration will led to the shift of equilibrium  to the left ( reactant  side)  .The concentration of  reactant  increase  as that of product decrease.
