Hi Lilian! To find the order, you need to first start with a reactant. If you're looking for the order of reactant A, you want to pick two experiments that have different concentrations of A, but the same concentrations for B. You could pick Experiments 1 and 2 for that. Then, you can use an equation:
Plug in the rates for each experiment as well as the concentrations of A for each experiment (Conc. of A from Exp. 2 on top and Conc. of A from Exp 1 on the bottom). solve for X. (Remember that the left side turns into (A2/A1)^x when you simplify).
Once you solve, the value of X represents the order of Reactant A. Then, do the same thing for B and C:

Hope this helps! Let us know if you have any other questions :)
The rate equation will be r=k [A]2[C} The order with respect to reactant A is second order, to reactant B is zero order and for reactant C is first order. Here's the solutions:
From reactant B you can see that the rate does not change after multiply by 1.5*square. this shows that the rate of the reaction does not depend on the concentration of reactant B.
hope that this get to help you!
