28. For the aqueous reaction I2 + HPO(OH)2 + H₂O → PO(OH)3 + 2 I¯ + 2 H* the following mechanism is proposed: HPO(OH)₂ P(OH)3 P(OH)3 + 12 → IP(OH)3* + I¯ IP(OH)3 + H₂O → PO(OH)3 + I + 2 H+ fast, unfavorable slow, irreversible fast Which observation is consistent with this mechanism? (A) The reaction is first order in both HPO(OH)2 and I₂. (B) The reaction rate is independent of the I₂ concentration. (C) The reaction goes faster as the concentration of H* is increased. (D) The reaction goes slower as the concentration of I- is increased.
