The activation energy of a reaction going on its own is 20 kj. If the reaction was treated with a catalyst, which would most lik ely represent the amount of energy needed to start a reaction?
2 answers:
Answer:
15 kJ
Explanation:
We need to know the following;
what is activation energy?
Activation energy is the minimum energy required by reactants for a chemical reaction to take place. What are catalysts?
Catalysts are molecules or substances that speed up the rate of a chemical reaction. In other words, catalysts increase the speed at which products are formed from reactants. How do catalysts speed up reactions?
Catalysts speed the rate of chemical reactions by lowering the activation energy of the reactants. When activation energy is lowered, reactants require less energy for the reaction to occur which easily achieved making the reaction proceed faster. Therefore, in presence of a catalyst, the new activation energy should be lower than the initial value of activation energy.
