Two energy levels of a molecule are separated by 10^-20 J. The degeneracy of the higher level is twice that of the lower level. Given k=1.38×10-23 J/K, calculate
(a) The relative populations of the levels at 0 °C.
(b) The temperature at which they are equally populated.
Calculate the uncertainty (in nm) in the position of an electron with the velocity of 2.00x103 m/s (the velocity is the same as in the preceding problem) and the uncertainty in the velocity is 1%. (2 significant figures are plenty).
This equation means that no matter how much carbon monoxide and oxygen gas is added to the flask, only 2 moles of CO and 1 mole of O2 will react to make two moles of Co2.
