Question

Help please! I'm not sure how to do this...However my guess is that it's either k [A][B]2 or k [A][B]

The following reaction: Was studied by measuring the [A] as a function of time. Reactant B was always present in excess and it was assumed that the [B] remained essentially constant during the reaction. Shown below is a table of the [A] as a function of time, in seconds. In the first experiment, [B] = 1.0 M and in the second experiment, [B] = 2.0 M. Also shown are the plots of these data which gave linear relationships, ln[A] versus time. Use these data to determine the form of the rate equation for this reaction. you have only one attempt to answer this question. The experimental rate equation has the form: rate = k [A] rate = k [B] rate = k [A][B]^2 rate = k [A][B] rate = k [A]^2

Explanation / Answer

The graph given represent a second order reaction kinetics.

Henc, the answer is

rate = k [A]2
