please help with tate constant. i have this equation but dont know what to use as values to find k. trying to find the rate
please help with tate constant. i have this equation but dont know what to use as values to find k.
trying to find the rate constant in the table and the values of m, n, p, and rate . no specific question .
dont have conc of acetone , need help

What is the overall order of the iodination reaction? 2. If you changed each concentration of acetone, iodine and hydrochloric acid by a factor of 3, by what factor would you expect the rate of the reaction to change? Show how you determined your answer! 3. Suppose you did not swirl reaction mixture #3 over a white piece of paper next to flask containing a clear solution (reference). a. Describe how the time measured for the reaction of mixture #3 will be affected by this error. ** b. Now state how the rate of reaction for mixture #3 will be affected. ** c. Next explain how the value of the rate constant calculated for mixture #3 will be affected. * ** For each of these, don't just respond that the values would be inaccurate or skewed.
