Homework Help: chemistry

Posted by elvis on Saturday, February 18, 2012 at 9:18pm.

Given this data in a study on how the rate of a reaction was affected by the concentration of the reactants


Initial Rate,
RUN #(A, M) (B, M) (C, M) (mol L-1 s-1
1 0.200 0.100 0.600 5.00
2 0.200 0.400 0.400 80.0
3 0.600 0.100 0.200 15.0
4 0.200 0.100 0.200 5.00
5 0.200 0.200 0.400 20.0


The rate constant for this reaction (all in the same units) is


a. 6667 b. 208 c. 2083 d. 139 e. 2500

help me!

The secret here is to determine the order of the reaction. For example, it is zero order in C. Do you know how to do the others? After you determine the orders, then k is determined as in your post above.

Saw the other post didnt help at all but I need the answer and simple step by step solution
