Response:
In the forward direction
Explanation:
The reaction quotient for an equilibrium reaction reflects the relative quantities of the products and reactants available at a specific point during the reaction period. When Q < Kc, the reaction advances forward. If Q > Kc, it goes in reverse. When Q = Kc, the system is in equilibrium. The ratio of concentrations of products to reactants is calculated, with each raised to their respective stoichiometric coefficients. Concentration of solids and liquids remains constant and hence isn't included in the expression. For this reaction:
The expression is:
Given,
[Cl⁻] = 0.50 mol/L; [ClO₃⁻] = 0.32 mol/L; [ClO⁻] = 0.24 mol/L
Thus, 
Q = 5.7870 ![Q=\frac {[CIO_3^{-}][Cl^{-}]^2}{[CIO^{-}]^3}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%20%7B%5BCIO_3%5E%7B-%7D%5D%5BCl%5E%7B-%7D%5D%5E2%7D%7B%5BCIO%5E%7B-%7D%5D%5E3%7D)
Since Q < Kc (
)
Therefore, the reaction will move in the forward direction.
Although I may not be the smartest, I can definitely answer.
This represents a chemical change because the substances' chemical identities were altered. The fizzing was a clear sign, and the temperature increase was another indicator of the reaction.
