Consider the general rate law expression rate=k [R1]u [R2]v\text{rate} = k\,[R_1]^{u}\,[R_2]^{v} for a reaction between reactants R1R_1 and R2R_2. (1) Part 1: (a) Explain what is meant by the order of a reaction with respect to an individual reactant and by the overall order of the reaction. Include how each concept is reflected in the rate law. (2) Part 2: (b) Describe how comparing initial rates from a series of experiments allows a chemist to determine the order with respect to a given reactant, even when the rate constant kk is unknown. (3) Part 3: (c) For the reaction 2F+G→products2F + G \rightarrow \text{products}, outline an experimental strategy that would reveal whether FF is zero order, specifying the measurements that would be taken and the reasoning that leads to the conclusion.
