An electronic system with 12 T-electrons (all of them in conjugation) was treated as a particle in a 2-D box of size of 3Å x 6Å. Calculate the wavelength corresponding to the lowest energy electronic transition for this system.

If  3A + B -- >  C And A is decreasing at a rate of 0.9 M/s Then C is increasing a rate of _____

Particles can collide in any formation and a bond will be formed if the particles speed is high True O False

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. First Order; because of a straight line on a…
