Eats PI L la To determine the stability of kinetomycin, a pharmacist dissolves an unknown amount of the drug in one litre of a saline solution. Samples are then taken at various times and sent to lab 10p allalysis. The following data are reported by the lab. Time (hr) Amount (mg) 3.5 3. Zero-order; because of a straight line on a semilog graph. 4. Zero-order; because of a straight line on a linear graph. 2. Which of the following statements is CORRECT for a ZERO-ORDER process? 1. The rate is independent of the amount or concentration of the drug. 2: The half-life is independent of the amount or concentration of the drug. 3: The rate constant is dependent on the amount or concentration of the drug. 4: The unit of rate constant is 1/time. 521 6.5 445 I. Please answer the following two multiple choice questions: 1. Please plot the above data on both linear and semilog graphs. What is the order of degradation process of kinetomycin? Why? 1.

Rate of Reaction Do all colliding particles react and form new products? What is the minimum amount of energy needed for the reaction to occur?
answer 1 to 10 blank spaces
Concentration Time (1) Concentration Time (s) b. 19) The instantaneous rate at any point in graph b can be found by A) subtracting the final time from the initial time and dividing by the concentration. B) subtracting the final concentration from the initial concentration and dividing by the time interval. C) taking the average of all rates found every 100 s. D) drawing a line tangent to the curve at the initial and final times, and then averaging. E) drawing a line tangent to the curve at that point.
When fitting data to a best fit line, a correlation coefficient (R2) is determined and used to evaluate the quality of fit. The best fit of the data will have an R² value closest or equal to zero (0). closest or equal to one (1). equal to the rate of the reaction occurring. equal to the rate constant of the reaction occurring.
