Answer question 7 Problem 5: Given the following laboratory data containing the disappearance of a chemical in water,do the data fit a zero-order, first- order, or second-order rate expression? Provide sufficientjustification for your answer, and report the correct rate constant in the correct units.Time, h0Concentration, mg/L 1000.561137214355.0 0.67Problem 6: The radioactive nuclide P32 has a half-life of 15.3 days. How long would a wastecontaining 10 mg/L of this nuclide have to be stored in order to reduce the concentration to 0.7mg/L? (1Problem 7: In a study it was found that 39 percent of the coliform organisms died within 9 h and67 percent died within 20 h. If the rate of die-off followed first-order kinetics and wereproportional to the number remaining, how long would it take to obtain 99.9 percent reduction incoliform organisms?

PLEASE ANSWER ONLY NUMBER 2 AND Use μ=0.6 THIS IS THE FORMULA BUT I COULDNT GET THE ANSWER BECAUSE I DON'T KNOW THE VALUE OF GAMMA (?). I JUST REPLACE THE VALUE OF μ OF .6 ???=???/?? =0.6[24(11.175)( ?)+115.2 ? / 200? PS: AND MAYBE YOU CAN TEACH ME WHAT IS THE VALUE OF GAMMA IN HERE BECUASE I DON'T KNOW. IF I KNOW THE VALUE OF IT I WOULD NOT ASK HERE.

Sample problem 2/2 A particle moves along the x-axis with an initial velocity v, = 50 m/s at the origin when t = 0. For the first 4 seconds it has no acceleration, and thereafter it is acted on by a retarding force which gives it a constant acceleration a, = -10 m/s?. Calculate the velocity and the x-coordinate of the particle for the conditions of t = 8 s and t = 12 s and find the maximum positive x-coordinate reached by the particle. Solve the problem using the equations of constant acceleration 2- v + 2a(s - s,) or s-s, +t
