  rate = kab… a) for the reaction 2A + B –> C + D if A is a first order reactant and B is a second order reactant, and kAB is 2.4 x 103 M-2s-1, and the rate of the reaction is 3.55 x 10-2 M/s when is 2.3 x 10-5M, solve for the concentration of B b) for the reaction 3A + 4B –> C If the rate of the reaction is 50 M/s when the concentration of A is 0.85M and the concentration of B is 0.93M (both are second order reactants), solve for the rate constant.

  a) Describe how i) a change in pressure and ii) a change in temperature can influence the rate of a chemical reaction.   b) How does the rate law account for the following factors that can affect the rate of a chemical reaction? i) a change of concentration of one of the reactants. ii) the reaction occurring at different temperatures.

A 68-year-old patient with a history of Parkinson’s Disease presents with increased postural sway and frequent “freezing” episodes during household ambulation. During today’s session, the physical therapist has the patient practice walking through a narrow hallway while simultaneously naming various types of fruit to address the patient’s difficulty with divided attention during functional mobility. What CPT code is most appropriate for this specific intervention, and what is the primary clinical justification?
