Multiple Choice

Given the initial rate data for the reaction A + B ? C, determine the rate expression for the reaction. $$\begin{array} { l l l } { [ \mathrm { A } ] , \mathrm { M } } & { [ \mathrm { B } ] , \mathrm { M } } & \Delta [ \mathrm { C } ] / \Delta t \text { (initial) } \mathrm { M } / \mathrm { s } \\\hline 0.0344 & 0.160 & 2.11 \times 10 ^ { - 2 } \\0.0516 & 0.160 & 3.17 \times 10 ^ { - 2 } \\0.0344 & 0.272 & 6.10 \times 10 ^ { - 2 }\end{array}$$

• A) \(\frac { \Delta [ \mathrm { C } ] } { \Delta t } = 3.84 \mathrm { M } ^ { - 1 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] [ \mathrm { B } ]\)
• B) \(\frac { \Delta [ \mathrm { C } ] } { \Delta t } = 24.0 \mathrm { M } ^ { - 2 } \mathrm {~s} ^ { - 1 } [ \mathrm {~A} ] [ \mathrm { B } ] ^ { 2 }\)
