ss7ja [257]

Answer:

The forward reaction is exothermic.

Explanation:

  • Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
  • When the mixture turned darker brown, this means that the reaction is shifted towards the left direction (reactants side).
  • The temperature is increased and the reaction shifted to the reverse direction, this means that the forward direction is exothermic.
  • Exothermic reaction releases heat and when increasing the temperature, the reaction will be shifted to the reverse direction to suppress the effect of increasing the temperature.
  • <em>So the right choice is: The forward reaction is exothermic. </em>
