andrew-mc [135]

 If more   heat  is removed from the reaction the rate of reaction change as below to counter the action

The rate of the  <em>forward reaction increase</em> and produces more   <em>zinc chloride</em>


<u><em>      explanation</em></u>

  • <u><em> </em></u>The reaction of  zinc and HCl  to produce ZnCl and H2 <u><em>is </em></u> exothermic reaction,  heat  is produced as one product   and by  removing  heat  it favor   forward reaction
  • The position  of equilibrium  moves to the right since  removing  heat led to decrease of temperature  and more  zinc chloride   is produced.
