(25 points) Quantitatively show, using entropy as the criteria, that the boiling of acetone at 70°C and 1 atm is spontaneous: C$_3$H$_6$O ($l$) {343K, 1 atm} $\rightarrow$ C$_3$H$_6$O ($g$) {343K, 1 atm} Possibly useful info: C$_p$ (liquid) = 125.5 J/mole K C$_p$ (gas) = 75.0 J/mole K $\Delta$H$_{vaporization}$ (329 K, 1 atm) = 31.0 kJ/mole At 1 atm, acetone boils reversibly at 329 K Do your results satisfy the Clausius Inequality?

Problem #2 (20 points) - Two Short Probability Problems a.) (12 points) A store opens for business at 9:00 AM and suppose that customers enter this store according to a stationary Poisson process with a constant rate of 40 customers per hour. Of these customers entering the school, 40% are female and 60% are males. Compute the probability that the 5th male enters the store between 9:15 AM and 9:20 AM. b.) (8 points) Suppose that a person invests in four stocks and that the return from each stock are normal random variables with $X_1 \sim N(20, 18)$, $X_2 \sim N(25, 10)$, $X_3 \sim N(15, 5)$ and $X_4 \sim N(8, 3)$ in units of hundreds of dollars. Compute the probability that the average return of all four stocks $X_{average} = \frac{X_1 + X_2 + X_3 + X_4}{4}$, is between $15 hundred and $18 hundred.
