HELP?
Expt [NO], M [Cl2], M Rate of Reaction
1 0.0125 0.0255 2.27 * 10-5
2 0.0125 0.0510 4.55 * 10-5
3 0.0250 0.0255 9.08 * 10-5

Isnt it right that NO has 2.order and Cl2 1.order ?

yes

anonymous · Answer

because when i calculated the rate constant (k) = 2.27*10^-5/(0.0125)^2(0.0255) = i got 5.7 when the right answere is 5.7 * 10^-2

I don't see anything wrong with your method.  In fact, if you plug in the value for k that you say is correct  (say for expt 1) and calculate the rate, you will not get 2.27E-05.
Try it.
