The diagram above shows the free energy G for several possible
states (gray lines) of a chemical reaction. The black arrows
represent possible transitions between these states, and the
brackets represent the corresponding free energy differences.
Consider the meaning of the different terms in the relation:
?G = ?G°' + RTlnQ
Select the option which most closely corresponds to each
description.

The figure shows part of the energy level diagram of a certain atom. The energy spacing between levels 1 and 2 is twice that between 2 and 3
Part A) The figure shows part of the energy level diagram of a certain atom. The energy spacing between levels 1 and 2 is twice that between 2 and 3. If an electron makes a transition from level 3 to level 2, the radiation of wavelength A is emitted. What possible radiation wavelengths might be produced by other transitions between the three energy levels?Part B)What is the energy required to remove the electron from a hydrogen atom in the n 11...

A certain type of atom
(not hydrogen) has three energy levels numbered 1, 2, and
3, as shown in the upper illustration. There are three possible
transitions between these levels that lead to emission of a photon:
3 ® 1, 3 ® 2, and 2 ® 1.
The lower illustration shows the emission spectrum from a gas of
these atoms. There are three emission lines, A, B, and C.
