 P: 1 I need to find the variable m in the following equation rate=k(acetone)m(I2)n(H+)p Here is our expirmental data Exp. 1 10 ml of 4 M acetone + 10 ml of 1 M HCl + 10 ml 0.005 M I2 reacted in 68 sec. Exp. 2 20 ml of 4 M acetone + 10 ml of 1 M HCl + 10 ml 0.005 M I2 reacted in 27.6 sec. I calculated the initial concentration of each to be Exp. 1 (Acetone)=0.8 M (H+)=0.2M (I2)=0.001M Exp. 1 (Acetone)=1.6 M (H+)=0.2M (I2)=0.001M I found the rate of reaction to be Exp. 1 = 1.47 * 10-5 Exp. 2 = 3.63 * 10-5 Then I plugged the data into the equation rate=k(acetone)m(I2)n(H+)p and solved for "m" but i got 1.26 My question is whether or not this number is even close and if it is should I just round it to 1 or what is the correct answer?
