Chemistry
Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the following reaction equation. 2h202(aq) →2h20(/) + 02(g) the activation energy for this reaction is 75 kj/mol. in the presence of a metal catalyst the activation energy is lowered to 49 kj/mol. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the metal-catalyzed reaction at 25°c?

Ответ:
Answer : The temperature for non-catalyzed reaction needed will be 456 K
Explanation :
Activation energy : The energy required to initiate the reaction is known as activation energy.
According to the Arrhenius equation,
Since, the rate for both the reaction are equal.
where,
Now put all the given values in the above formula 1, we get:
Therefore, the temperature for non-catalyzed reaction needed will be 456 K
