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

Answer 1

This is a second order reaction, as the graph of 1/[Concentration] vs time is linear. Thus, the units of k are M^-1s^-1. When you plot the data points =given according to this line, you get a slope of roughly 0.0133; this is the rate constant.
