Question

For  A⟶products , time and concentration data were collected and plotted as shown.

[𝐀] (𝐌)  𝐭 (𝐬)

0.600  00.0

0.484  30.0

0.405  60.0

0.349  90.0

A plot of the concentration of A versus time is concave up

and decreases with time.A plot of the natural logarithm of the concentration of A versus time is concave up and decreases with time.A plot of one over the concentration of A versus time increases linearly with time.

Determine the reaction order, the rate constant, and the units of the rate constant.

Answer 1

If you plot the data, you will get a straight line with slope=0.013. Use your calculator to determine the regression line and you will get the slope of the line. Since the y axis is the reciprocal of the concentration, you are dealing with a second order reaction, the slope of the line will be the reaction constant; in this case 0.0133 M^-1sec^-1.
