In a magnetic sector (single-focusing) mass spectrometer, it might be reasonable under some circumstances to monitor one m/z value, to then monitor a second m/z, and to repeat this pattern in a cyclic manner. rapidly switching between two accelerating voltages while keeping all other conditions constant is called peak matching.
a) derive a general expression that related the ratio of the accelerating voltages to the ratio of the corresponding m/z values.
b) use this equation to calculate m/z of unknown peak if m/z of the ion used as a standard, cf3+ is 69.00 and the ratio of vunknown/vstandard is 0.976034.
(c) based on your answer in part (b), and the assumption that the unknown is an organic compound that has a mass of 143, drnw some conclusions about your answer in part (b ), and about the compound.

(c) the equilibrium constant is zero. (d) the value of the equilibrium constant does not show how quickly a reaction comes to equilibrium.
