Select the correct answer.
Sladkaya [172]

Answer:

  • <u><em>Option D. There will be a shift toward the reactants.</em></u>

Explanation:

The reaction is:

       PCl_5(g)+heat\rightleftharpoons PCl_3(g)+Cl_2(g)

The application of LeChatelier's principle leads to consider the <em>heat</em> as a <em>reactant</em> or a product depending on if it is on the left side or the right side.

In this reaction, the <em>heat</em> is on the left side, thus it must be considered a <em>reactant</em>.

Decreasing the temperature is equivalent to remove or consume heat. Thus, the reaction must shif to the left to compensate that reduction of heat. That is the reverse reaction shall be favored.

In conclusion, <em>there will be a shift toward the reactants.</em>
