A mass spectrograph is used to measure the masses of ions, or to separate ions of different masses. In one design for such an instrument, ions with mass m and charge q are accelerated through a potential difference V. They then enter a uniform magnetic field that is perpendicular to their velocity and are deflected in a semicircular path of radius R. A detector measures where the ions complete the semicircle and from this it is easy to calculate R.
Derive the equation for calculating the mass of the ion from measurements of B, V, R, and q.
What potential difference V is needed so that singly ionized 12C atoms will have R=50.0 cm in a0.150-T magnetic field?
Do you think that this beam separation is sufficient for the two ions to be distinguished?

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
