Question

I'm really stuck with this one. Here's the rate law and the data that is needed. I appreciate any help

Rate= k[I2]X{[H+]Y[CH3COCH3]Z



Column 1 - Trial
Column 2 - Volume of 0.0010 M I2
Column 3 - Volume of 0.050 M HCl
Column 4 - Volume of 1.0 M acetone
Column 5 - Volume of water Temperature (degrees C)
Column 6 - Reaction time
A 5.0 10.0 10.0 25.0 25.0 130
B 10.0 10.0 10.0 20.0 25.0 249
C 10.0 20.0 10.0 10.0 25.0 128
D 10.0 10.0 20.0 10.0 25.0 131
E 10.0 10.0 10.0 20.0 42.4 38

What is the rate constant at 25.0 degrees C based on the data collected for trial B? Assume that the relative rate is equal to the actual rate in molar per second.

Answer 1

A 5.0 10.0 10.0 25.0 25.0 130
I copied the first row you had. I count 7 columns but you identify only 6.

Answer 2

The 7th is reaction time in seconds.
