Question

You are part of a team designing a fusion generator that induces the following reactions. 21H + 21H → 32He + 10n 21H + 21H → 31H + 11H

Its power requirements are 2.49 ✕ 109 J/s and it is to be fueled by an equal number of the two different D-D reactions, each yielding Q values of 3.27 MeV and 4.03 MeV, respectively. Determine the hourly rate at which the generator will consume fuel. (Enter your answer in g/h. Assume mD = 2.0141 u for the mass of deuterium.)
