We've coined a word, ecosystem, for the systems on Earth that affect life systems. The term can be very useful because so many things can be described as systems.
The chemical element that is formed when I-131 undergoes beta-minus decay is Xe.
<h3>What is a beta minus decay?</h3>
A beta minus decay is one in which an electron is changed into a proton. The atomic number of the daughter nucleus will increase by one unit and is one place after the parent in the periodic table.

Answer : The temperature for non-catalyzed reaction will be,
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 = 70.0 kJ/mol
= activation energy for catalyzed reaction = 42.0 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 will be,
