Please answer the question Learning Goal:To understand how to use integrated rate laws to solve for concentration.A car starts at mile marker 145 on a highway and drives at 55 mi/hr in the direction of decreasingmarker numbers. What mile marker will the car reach after 2 hours?This problem can easily be solved by calculating how far the car travels and subtracting that distancefrom the starting marker of 145.55 mi/hr x 2 hr = 110 miles traveledmilemarker 145 – 110 miles = milemarker 35If we were to write a formula for this calculation, we might express it as follows:milemarker = milemarker, – (speed × time)where milemarker is the current milemarker and milemarker, is the initial milemarker.Similarly, the integrated rate law for a zero-order reaction is expressed as follows:[A] = [A]o – rate x timeor[A] = [A]o – ktsincerate = k[A]o = kA zero-order reaction (Figure 1)proceeds uniformly over time. In other words, the rate does not changeas the reactant concentration changes. In contrast, first-order reaction rates (Figure 2) do change overtime as the reactant concentration changes.Because the rate of a first-order reaction is nonuniform, its integrated rate law is slightly morecomplicated than that of a zero-order reaction.The integrated rate law for a first-order reaction is expressed as follows:[A] = [A]ge¬ktwhere k is the rate constant for this reaction.The integrated rate law for a second-order reaction is expressed as follows:1JA = kt +where k is the rate constant for this reaction. The rate constant for a certain reaction is k = 2.20×103 s. If the initial reactant concentration was 0.650 M, what will the concentration be after 9.00 minutes?Express your answer with the appropriate units.• View Available Hint(s)Templates Symbols undo redo reset keyboard shortcuts help[A]t =ValueUnits
