Answer:
goes down regardless of whether the reaction is exothermic or endothermic
Explanation:
The activation energy is the minimum energy the reactants in a chemical reaction will have to reach in order to be transformed into products.
Hence, the higher the activation energy of a reaction, the lower the reaction rate and the lower the activation energy of a reaction, the higher the reaction rate.
Activation energy is independent of whether a reaction is exothermic or endothermic.
Therefore, as activation energy increases, reaction rate goes down irrespective of whether is is exothermic or otherwise.
The reaction rate goes down regardless of whether the reaction is exothermic or endothermic.
• The minimum amount of energy, which must be given for compounds to form in a chemical reaction is termed as the activation energy.
• With the increase in activation energy, it signifies that more energy is needed for the reaction to take place.
• Therefore, with increase in activation energy it can be stated that the reaction rate has decreased.
• The activation energy is independent of the fact that whether the reaction is endothermic or exothermic.
Thus, as activation energy increases, the reaction rate decreases regardless of the fact that whether the reaction is exothermic or endothermic.
