The ionic reaction 3I- + S2O82- → 2SO42- + I3- is found to be described by the experimental rate equation: Rate = k[I-][S2O82-]. This suggests that:

Verified Solution4 OptionsUpdated: October 2026👁️1 View

1A slow step in the overall reaction sequence may involve the collision of a single I- ion with a single S2O82- ion.✓
2The rate of reaction is inhibited by the presence of I3-.
3There must be only one step in the overall reaction since the rate is first order in both reactants.
4The reaction occurs when three iodide ions collide simultaneously with one S2O82- ion.

Correct answer

A slow step in the overall reaction sequence may involve the collision of a single I- ion with a single S2O82- ion.
