Answer:
The reason that the balloon shrinks is because when the temperature drops, helium becomes more dense then it already is. So what happens is that its molecules lose energy, slows down and moves closer together to conserve heat and this decreases the volume inside the balloon because the helium molecules are moving closer together, rather than outward toward the shell of the balloon which cause the balloon to swell then shrink. The gas law that causes this to happen is the Charles law.

<span>Activation Energy Ea = 249 x 10^3 J/mol
Frequency Factor = 1.6 Ă— 1014 sâ’1
Rate of reation is twice as fast with temperature change so k1/k2 = 1/2.
Temperature T1 = 730.6, T2 =?
Gas constant R = 8.314 J/ mole-K
We have Arrhenius equation ln (k1 / k2) = (Ea / R) x [(1/T1) - (1/T2)]
ln(1/2) = ((249 x 10^3) / 8.314) x [(1/T2) - (1/730.6)]
ln(1/2) = 29.95 x 10^3 x [(1/T2) - 0.0013687]
-0.69315 / (29.95 x 10^3) = (1/T2) - 0.0013687
(1/T2) - 0.0013687 = - 2.3 x 10^-5
1 / T2 = 0.0013455
T2 = 743.18 k</span>
