The decomposition of ozone is proposed to occur through different mechanisms: 2 03 23 02 The experimental rate law for this reaction has been found to be: = k [0312 Rate [02] Using the rate law given above, which of the following graphs best represents how the concentration of O3 changes with time according to the experimental rate law given above? 10311 time [03] time [03] time [031
It's a lot, but I really don't
understand these questions. Please explain! Thank you!
QUESTION 2 What volume (in L) is occupied by 1.29 moles of gas at -24.5 °C with a pressure of 704 mm Hg? QUESTION 3 A piston with a volume of 800.8 mL is filled with a gas at 304.1 K and 717.4 mm Hg. The piston is then compressed by 192.4 mL and cooled to 243 K. What is the pressure in atm) of the...
Please give solutions with detailed explanations. I appreciate
neat hand writing. Thanks a lot.
3. (a) Show that [e-21/a (1 + 2r/a + 2r2/a?)] = -4r²e-20/a. (b) Use this result to show that the ground state wavefunction of the hydrogen atom is properly normalized: S• P(r) dr = 1. In astronomy, analysis of the photons emitted from very hot plasmas (such as are ob- served at the surface of stars, or during supernova explosions) commonly reveals spec- tral lines from...
Consider the signal f[k] illustrated below 3 2 1 (a) Using the definition, provide the DTFT of flk]. (b) Express f [kas a rect function. Use the DTFT pair to solve for the DTFT (it should look a lot different from the previous solution) c) Verify that both of your solutions are, in actuality, the same by evaluating them at 0, T/2, T

Solow-Romer Model 2. Let the production function for output be 11/2 YA,K/2L2 Compared to the model described in the Chapter 6 Appendix, the exponent on capital has been increased from 1/3 to 1/2 above and decreased on labor from 2/3 to 1/2 to preserve constant returns to scale in objects. All of the other assumptions from lecture and/or from the Chapter 6 Appendix are the same What is the growth rate of output per worker along a balanced growth path?...
5. Three boxes are numbered 1, 2 and 3. For k 1, 2, 3, box k contains k blue marbles and 5 - k red marbles. In a two-step experiment, a box is selected and 2 marbles are drawn from it without replacement. If the probability of selecting box k is proportional to k, then the probability that two marbles drawn have different colours is 6. Two balls are.dropped in such a way that each ball is equally likely to...
What is the smallest unit of free charge that has been observed experimentally? plusminus 1/3 e plusminus 2/3 e plusminus 1.602 times 10^-19 C plusminus 1.000 C plusminus5.0 times 10^+27 C What is true concerning the charge in the diagram to the right according to the electric field lines shown? The charge must be negative. The charge must be positive. Nothing can be determined about the charge from the field lines. A glass rod is rubbed with silk and becomes...
STANDARD ENTHALPY AND ENTROPY CHANGES OF A REACTION INTRODUCTION (1) Part 3, Mes Consider the following equilibrium system sscc Fe(a)SCNag) FeSCNP(o) The equilibrium constant, K of this system is (2) resCN KTeSCN Finding K for this system using a colouurimeter and absorhance values has already been described in the "Determination of an Equilibrium Constant" experiment. A similar method is used in this experiment, but the temperature is varied so give values of the equilibrium constant at different temperatures. From the...
