Multiple Choice

Given the initial rate data for the reaction A + B ? C, determine the rate expression for the reaction. $$\begin{array} { l l l } { [ \mathrm { A } ] , \mathrm { M } } & { [ \mathrm { B } ] , \mathrm { M } } & \Delta [ \mathrm { C } ] / \Delta t \text { (initial) } \mathrm { M } / \mathrm { s } \\\hline 0.215 & 0.150 & 5.81 \times 10 ^ { - 4 } \\0.215 & 0.300 & 1.16 \times 10 ^ { - 3 } \\0.430 & 0.150 & 2.32 \times 10 ^ { - 3 }\end{array}$$

• A) \(\frac { \Delta [ \mathrm { C } ] } { \Delta t } = 1.80 \times 10 ^ { - 2 } \mathrm { M } ^ { - 1 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] [ \mathrm { B } ]\)
• B) \(\frac { \Delta [ \mathrm { C } ] } { \Delta t } = 3.60 \times 10 ^ { - 2 } \mathrm { M } ^ { - 1 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] [ \mathrm { B } ]\)
• C) \(\frac { \Delta [ \mathrm { C } ] } { \Delta t } = 1.20 \times 10 ^ { - 1 } \mathrm { M } ^ { - 2 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] [ \mathrm { B } ] ^ { 2 }\)
• D) \(\frac { \Delta [ \mathrm { C } ] } { \Delta t } = 5.57 \times 10 ^ { - 1 } \mathrm { M } ^ { - 3 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] ^ { 2 } [ \mathrm {~B} ] ^ { 2 }\)
• E) \(\frac { \Delta [ \mathrm { C } ] } { \Delta t } = 8.37 \times 10 ^ { - 2 } \mathrm { M } ^ { - 2 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] ^ { 2 } [ \mathrm {~B} ]\)
