Use the fоllоwing stаndаrd reductiоn potentiаls to determine which species is the best oxidizing agent. O2(g) + 4 H+(aq) + 4 e– → 2 H2O() E° = +1.229 V Hg22+(aq) + 2 e– → 2 Hg() E° = +0.789 V I2(s) + 2 e– → 2 I–(aq) E° = +0.535 V

The distance between gas particles is large in comparison to their size. 3. The average kinetic energy of gas particles is proportional to the kelvin temperature of the gas.
