Trial [X] [Y] Rate
1 0.20 M 0.15 M 2.4 × 10-2 M/min
2 0.20 M 0.30 M 4.8 × 10-2 M/min
3 0.40 M 0.30 M 19.2 × 10-2 M/min

Question

Determine the rate law, including the values of the orders and rate law constant, for the following reaction using the experimental data provided. 

X + Y  products


Trial	   [X]	            [Y]	           Rate
1	0.20 M	0.15 M	2.4 × 10-2 M/min
2	0.20 M	0.30 M	4.8 × 10-2 M/min
3	0.40 M	0.30 M	19.2 × 10-2 M/min

i started out with 1 and 2 becuase they just look easiest to start with.... basically.... the rate increased by  4.8/2.4=2. that equals y
so k{x}^n{y}^m

You have to correlate the change in concentration to the change in the rate. How did  the concentration of Y change between trials 1 and 2?
