Question

The following reaction occurs in basic solution:

OBr^—(aq) + PH₃(aq) → OH^—(aq) + PH₂Br(aq)

Given the initial rate data for the reaction at 25 °C,

Chemical reaction in basic solution with rate law options for OBr− and PH3.

Determine the rate law for the reaction and numerical value of the rate constant, k, with correct units.

Accepted Answer

rate = k([OBr⁻][PH₃])/[OH⁻]
k = 0.12 s⁻¹

Answer

rate = k[OBr⁻][PH₃][OH⁻]
k = 1.2×10⁷ M⁻²·s⁻¹

Answer

rate = k[OBr⁻]²[PH₃][OH⁻]
k = 8.0×10⁸ M⁻³·s⁻¹

Answer

rate = k[OBr⁻][PH₃]²[OH⁻]
k = 6.0×10⁸ M⁻³·s⁻¹
