An electron is confi ned to a linear region with a length of the same order as the diameter of an atom (about 100 pm). calculate the minimum uncertainties in its position and speed.

Explanation:

The minimum uncertainty position is 100 nm.

Therefore, by Heisenberg Uncertainty principal

ΔxΔp≥h/2

Δp≥h/(2Δx)

we know that

h= Js

Δx=

therefore,

therefore,

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
