Proposed reasons include strong electric fields at the surface, partial drying of reactants and evaporation that concentrates them.","posed_since":"","precise":"For bimolecular reactions in aqueous microdroplets of radius 1 to 50 micrometers, determine the true acceleration factor of the rate constant relative to bulk after correcting for evaporation, concentration changes, gas-phase reactions in the mass spectrometer inlet and ion-source chemistry, and identify the dominant cause (interfacial electric field, partial solvation, interfacial pH, charge). An answer is a corrected acceleration factor for benchmark reactions plus a mechanism that predicts it.","problem_ref":null,"references":"","settled_by":"In situ, inlet-free kinetic measurements (for example fluorescence or Raman in levitated droplets) matched to simulations of interfacial reaction free energies.","status_note":"","title":"Mechanism of reaction acceleration in microdroplets","topic_ref":"918cab5fffb6928d499834f70aaf71d4b8e0b2721de2faefb454f55dc900049a"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"2a05994131220df055ff4b914f635d3c25c7a85dbdeada30ba6bd157d14a9630","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"63908c56bd3111d0ae5272d02bcb5f852a1c5c1bee995e779e93f9702c738215","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"qzaHF66Hhjh511uZOPMhyNXTJwc98Pz5kAp-UQ2z923X0OPNS7LBvBnPAn00jk1z5kQzj-qQoZx4Sn8cagnFAA"},"schema":"pubphys.envelope/1"},"record_hash":"2a05994131220df055ff4b914f635d3c25c7a85dbdeada30ba6bd157d14a9630","leaf_index":843}
