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,
Determine therate law for the reaction andnumerical value of the rate constant, k, with correct units.

Accepted Answer

rate = k([$$OBr^{−}$$][PH_{3}])/[$$OH^{−}$$] k = 0.12 $$s^{−1}$$

Answer

rate = k[$$OBr^{−}$$][PH_{3}][$$OH^{−}$$] k = 1.2×$$10^{7}$$ $$M^{−2}$$·$$s^{−1}$$

Answer

rate = k[$$OBr^{−}$$]^{2}[PH_{3}][$$OH^{−}$$] k = 8.0×$$10^{8}$$ $$M^{−3}$$·$$s^{−1}$$

Answer

rate = k[$$OBr^{−}$$][PH_{3}]^{2}[$$OH^{−}$$] k = 6.0×$$10^{8}$$ $$M^{−3}$$·$$s^{−1}$$
