The explosion of the Ivy Mike hydrogen bomb. The hydrogen bomb was the first device able to achieve fusion energy gain factor significantly larger than 1.. A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state.
The reaction quotient plays a crucial role in understanding the direction and extent of a chemical reaction's progress towards equilibrium: Equilibrium condition: At equilibrium, the reaction quotient (Q) is equal to the equilibrium constant (K) for the reaction. This condition is represented as Q = K, indicating that the forward and reverse ...
The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...
Many host–guest complexes has 1:1 stoichiometry, but many others have more complex structures. The general equilibrium can be written as p A + q B ⇌ A p B q. The study of these complexes is important for supramolecular chemistry [24] [25] and molecular recognition.
By this definition, a saturated liquid has q = 0. A saturated vapor has q = 1. [3] An alternative definition is the 'equilibrium thermodynamic quality'. It can be used only for single-component mixtures (e.g. water with steam), and can take values < 0 (for sub-cooled fluids) and > 1 (for super-heated vapors):
a thermodynamic equilibrium constant, denoted by , is defined to be the value of the reaction quotient Q t when forward and reverse reactions occur at the same rate. At chemical equilibrium , the chemical composition of the mixture does not change with time, and the Gibbs free energy change Δ G {\displaystyle \Delta G} for the reaction is zero.
We can be sure this setup gives us the equilibrium levels as neither firm has an incentive to change their level of output as doing so will harm the firm at the benefit of their rival. Now substituting in q ∗ {\displaystyle q^{*}} for q 1 , q 2 {\displaystyle q_{1},q_{2}} and solving we obtain the symmetric (same for each firm) output ...
In the case of chemical reactions this is usually the number of particles or mole fractions, subject to the conservation of elements. At equilibrium, these will take on their equilibrium values, and the internal energy will be a function only of the chosen value of entropy . By the definition of the Legendre transform, the Helmholtz free energy ...
