D. All of the above. Developing medicine, analyzing compounds and producing new product such as plastic all have to deal with chemistry.
Alpha particle is the nuclear decay emission that has the weakest penetrating power. The correct option among all the options that are given in the question is the first option or option "1". Gamma is a type of radiation and so can be negated as a particle. Alpha particles have the largest radiation and so the weakest penetrating power.
The relation between rate constants at different temperatures, temperature and activation energy is known as Arrhenius equation
<u>Arrhenius equation</u>

For two temperatures

Where
Ea = ? = activation energy
k1 = 3.36 × 10⁴
T1=344 k
k2=7.69
T2=219K
R= gas constant = 8.314 J /molK
Putting values

Ea = (-69.69)/(-0.00166) = 41981.93 J/mol
Or
Activation energy is 42.0 kJ /mol
Well air pollution, lung cancer, global warming those are just a couple off if my head
