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.


..........(1)
where,
= activation energy for non-catalyzed reaction = 75 kJ/mol
= activation energy for catalyzed reaction = 49 kJ/mol
= temperature for non-catalyzed reaction = ?
= temperature for catalyzed reaction = 
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
It is C. Cations have positive charge. They get a positive charge when they lose an electron in their outer shell
