If two atoms collide in interstellar space the energy of the resulting molecule is so great that it — Physical Chemistry Chemistry Question
Interstellar production of H 2
If two atoms collide in interstellar space the energy of the resulting molecule is so great that it rapidly dissociates. Hydrogen atoms only react to give stable H2 molecules on the surface of dust particles. The dust particles absorb most of the excess energy and the...
Assuming steady-state conditions, use the above rate equations to find expressions for the ratios x2/x1 and x1/x0 , and evaluate these ratios.
Evaluate the steady state fractions x0, x1 and x2.
[If you were unable to determine the ratios in 2.6, use x2/x1 = a and x1/x0 = b and give the result algebraically.]
Evaluate the rate of production of H2 per dust particle in this model.
It is currently not possible to measure the rate of this reaction experimentally, but the... Limiting the number of atoms adsorbed on the particle to 2 leads to substantial error (at least a factor of two).
