Question

Report Question Report Questions do not need to be completed before leaving the laboratory, but we en- courage you to jot down your answers if time permits. They will be incorporated into the Report Template and graded for accuracy. See the rubric on Carmen for more information. Matthew performed an experiment with a reaction that is known to be first-order. However during data analysis he created a graph using the integrated rate law for a zero-order reac- tion. Which of the following graphs would Matthew observe if he plotted his data from the first-order reaction he studied using the zero-order integrated rate equation? Why?

Thanks again!

Answer 1

zeroth order = [A] = [A]_0 - kt so, plot of [A] vs + should give a straight line with a negative slope k First order = [A] = [A]_0 e^-kt ln[A] = ln[A]_0 - kt plot of ln[A] vs + will give a straight line with a negative slope. It means, if we plot first-order data using zeroth-order rate law, it will not be a straight line but slope will be negative. D is the answer.
