The bonding in H2 and D2 is identical as they only differ in the number of neutrons. (a) What is the ratio of the reduced masses for the H2 and D2 The reduced mass is given by: μ = à - à.

Fast forward scattering oscillations, relating with interference effects in the scattering process, were clearly observed for H2 products at H2(v′=0, j′=1) and H2(v′=0, j′=3) rovibrational.
The second is an indirect mechanism opened by a barrier resonance in which the transition state is able to rotate a fraction of a cycle before breaking apart into products.

A detailed investigation of the spatially anisotropic component of the laterally averaged molecular hydrogen/Ag() physisorption potential is presented. Experimentally derived rotationally inelastic transition probabilities for H2, D2, and HD, taken as a function of collision energy, are compared with those resulting from close-coupled quantum scattering calculations.
Time-independent quantum mechanical (TIQM) approach (helicity basis truncated at k = 2) has been used for computing differential and integral cross sections for the exchange reaction H- + D2 (v = 0, j = 0−4) → HD + D- and D- + H2 (v = 0, j = 0−3) → HD + H- in three dimensions on an accurate ab initio potential energy surface.

Except at ultrahigh pressures on the order of a few mega bars, where a transition to a metallic, atomic phase is expected, these solids are true molecular crystals in which the molecules retain their identityBrand: Springer US. This dissertation primarily focuses on two studies which bring forward new insights to this simplest chemical reaction: (i) scattering dynamics of H + D2 HD (v'=1, j') + D reaction at eV, and (ii) probing the dynamics of H + D2 reaction beyond the energy of the conical intersection of H3 surface at a collision energy of eV.

Ag^+ + e^- -->Ag. Now, to balance them, you need to have the same number of electrons in both reactions. In this case, you have two for the hydrogen and only one for the silver. So this is what you do: (Ag^+ + e^- -->Ag)2.
Multiply the complete second rxn by 2. Then add both half rxns together to get the final answer of: H2+2Ag^+ --> 2H^+ + 2Ag. The calculation of cross sections and rate constants for chemical reactions in the gas phase has long been a major problem in theoretical chemistry.
