Altitude is height above sea level. The density of air decreases with height. There are two reasons, at higher altitudes there is less air pushing down from above,and gravity is weaker farther from earths center.

Answer:
The reaction is first order.
Rate constant = 0.021 sec^-1
Explanation:
See the attached file for the explanation.
FN = Fe
Explanation:
Although the charge aren't the same, it should be equal to the magnitude of the forces. The coulomb force governs between both the nucleus and the electron, which is equal to the charge element.
The FN and Fe magnitudes somehow have to be equal, because the ordering does not apply in the multiplication.
There is a much more specific explanation, however, for such powers to be equivalent: they are the relationship pair of the third law of Newton, which has the same in scale and the direction opposite .
