Which other element is most likely to be a nonreactive gas?
2 answers:
Answer:
Choice D. Among the choices, (krypton) is likely to be the most similar to neon and behave as a non-reactive gas.
Explanation:
Columns in the periodic table are called "groups." Elements in the same group (i.e., same column of the periodic table) tend to have similar chemical properties.
In this example, neon is in the same right-most column of the periodic table. Since neon is a non-reactive gas, it is reasonable to infer that other elements in the same column would behave similarly.
Among the choices, krypton () is the only element in the same column. Thus, krypton would be the most likely element to be a nonreactive gas.

Answer:
k ≈ 9,56x10³ s⁻¹
Explanation:
It is possible to solve this question using Arrhenius formula:
Where:
k1: 1,35x10² s⁻¹
T1: 25,0°C + 273,15 = 298,15K
Ea = 55,5 kJ/mol
R = 8,314472x10⁻³ kJ/molK
k2 : ???
T2: 95,0°C+ 273,15K = 368,15K
Solving:
<em>k ≈ 9,56x10³ s⁻¹</em>
