Chapter 14, Problem 18QP

Consider the reaction:

$\text{X + Y}\underset{}{\to }\text{Z}$

From the following data, obtained at 360 K, (a) determine the order of the reaction, and (b) determine the initial rate of disappearance of X when the concentration of X is 0.30 M and that of Y is 0.40 M.

Initial Rate of Disappearance of X (M/s)	[X] (M)	[Y](M)
0.053	0.10	0.50
0.127	0.20	0.30
1.02	0.40	0.60
0.254	0.20	0.60
0.509	0.40	0.30
