How do I solve problems 2-5? Can I please have some help.

Assuming all volumes remain the same, if the 0.200MKI used in this experiment was replaced with 0.100MKI, a. How would this affect the rate of the reaction? b. How would this affect the rate constant? Complete the following two sentences for the following rate law: Rate =k[A]2[B]0[C]1 This reaction is order with respect to A order with respect to B, and order with respect to C. The overall order is and the units of the rate constant are Give a practical example of a reaction whose rate is measured
