A construction company has an expenditure rate of E(x)=e^0.13x dollars per day on a particular paving job and an income rate of I(x)=124.1−e^0.13x dollars per day on the same job, where x is the number of days from the start of the job. The company's profit on that job will equal total income less total expenditures. Profit will be maximized if the job ends at the optimum time, which is the point where the two curves meet. (a) Find the...

It has been found that in acid solution (greater than 1 M H^+) the rate expression for the reaction of H_2O_2 with I' is of the form rate = k_2[H_2O_2][T] where k_2 = 0.25 L^2 mol^-2 s^-1 at 25 degree C Therefore the rate law over the whole range of acidity from very acid solutions to a neutral solution is given by a two-term rate expression: rate = k_1[H_2O_2)[I^-] + k_2[H_2O_2)[I^-)[H^+) where k_j has the value of 0.0115 L mol'1...
