Working with lifetime and energy uncertainty

The lifetime of a molecule in a certian electronic state is 10e-10 s. What is the uncertianty in energy of this state? Give the answer in J and in J/mol.

Solution Preview

According to quantum mechanics, the uncertainity in energy and time is related by the formula,

dE dt >= h/(4pi)

where h=6.626 * 10^-34 JS is the ...
