EXPLANATION OF EQUATIONS USED WOULD BE HELPFUL! THANK YOU!

Consider the reaction A+BC with the following experimental data: Determine the rate law Rate=k[A][B]Rate=k[A]Rate=k[A][B]2Rate=k[A]2[B]Rate=k[A]2 Part 2 of 2 Determine the rate constant for the above reaction (don't put your units in the answer)
