You will need to generate a set of graphs to answer this question.

Concentration vs time data for the following decomposition reaction was collected at 300 K. The data is shown in the table below.

What is the rate constant for the reaction at this temperature (in units of min-1)?

H2O2(aq) → H2O(l) + 1/2 O2(g)

time (min) [H2O2](mol/L)
0 0.01750
500 0.00678
1000 0.00259

Answer #1

Plot of ln [H2O2] vs time is straight line. So reaction is first order in H2O2.

For a first order reaction ln [A] = ln [A]0 - kt

ln [A] versus t will be straight line with slope = -k, where k is rate constant

From the graph, the equation of best fit line is y = -4.0462 - 0.00190 x

Slope = -k = -0.00190

Rate constant, k = 0.00190 min-1
