In general the larger the positive q value for the reaction. Calculate the reaction q value.
The atom masses of the reactants and products are.
Q value formula physics. 3t d n 4he. The dt fusion reaction of deuterium and tritium is particularly interesting because of its potential of providing energy for the future. It can be determined from the masses of reactants and products.
M 3 t 3 0160 amum 2 d 2 0141 amum 1 n 1 0087 amum 4 he 4 0026 amuusing the mass energy equivalence we get the q. In this type of system the losses are high and the system has no overshoot. Over damped q 1 2.
Instead the system will exponential decay approaching the steady state value asymptotically after a step impulse is applied. Q value of dt fusion reaction. In nuclear physics and chemistry the q value for a reaction is the amount of energy absorbed or released during the nuclear reaction.
In physics and engineering the quality factor or q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. Q factor is alternatively defined as the ratio of a resonator s centre frequency to its bandwidth. The value relates to the enthalpy of a chemical reaction or the energy of radioactive decay products.
An over damped system has a q factor that is less than 1 2. It is approximately defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation. Q values affect reaction rates.
