Question 25: Calculate the rate of reaction in M/s when the concentration of X is 0.382 M, the concentration of Y is 0.156 M, and the concentration of Z is 0.0873 M. Give your answer to 3 Sig Figs. | Concentration of X (M) | Concentration of Y (M) | Concentration of Z (M) | Initial Rate (M/S) | |---|---|---|---| | 0.300 | 0.500 | 0.0100 | 0.0320 | | 0.300 | 0.500 | 0.0200 | 0.0640 | | 0.600 | 0.500 | 0.0200 | 0.0640 | | 0.600 | 0.250 | 0.0200 | 0.0160 | The answer is 0.0272 +/- 1.5%

46. If X and Y have the joint probability distribution f(-1,0) = 0, f(-1,1) = \frac{1}{4}, f(0,0) = \frac{1}{6}, f(0,1) = 0, f(1,0) = \frac{1}{12}, and f(1,1) = \frac{1}{2}, show that (a) cov(X, Y) = 0; (b) the two random variables are not independent. 49. If X1, X2, and X3 are independent and have the means 4, 9, and 3 and the variances 3, 7, and 5, find the mean and the variance of (a) Y = 2X1 - 3X2 + 4X3; (b) Z = X1 + 2X2 - X3.

The position x of a bowling ball rolling on a smooth floor as a function of time t is given by: x(t)=v0t+x0 , where v0=2.5m/s and x0=−5.0m . The polynomial relationship between position and time for the bowling ball is _______________. Using this relationship, what is the position of the bowling ball at times t=4.0s and t=8.0s ? From the coordinates obtained in Part B, find the slope of the position-time relationship for the bowling ball using the "rise over run" algortithm.

6. Yves Chauvin received 1/3 of the 2005 Nobel Prize in Chemistry for his proposal regarding the mechanism of olefin metathesis reaction. Using the example of \"ring opening metathesis polymerization\" (ROMP) of norbornene, show how his mechanism yields a polymer, and what its structure is. Draw critical intermediates, using either a Grubbs or Schrock type catalyst.
