Question

Given the initial rate data for the reaction A + B ? C, determine the rate law for the reaction. The reaction is catalyzed by molecule D.

[A],M                             [B], M                     [D], M                       ?[C]/?t(mol/L>s)

0.10                             0.20                        0.10                                2.58

0.10                             0.10                       0.10                                 1.29

0.24                            0.10                        0.20                                 2.58

0.10                            0.20                        0.20                                 5.16

a) ?[C]/?t = k[A][D]2

b) ?[C]/?t = k[A][B][D]

c) ?[C]/?t = k[B][D]

d) ?[C]/?t = k[A][B]

Explanation / Answer

when you increase the concentration of each reactant the rate of the reaction increases respectively so we need to include all the concentration in our rate equation.catalyst can be included in rate equation in case it is present in the rate determining step so the answer is b
