2) The quantity theory of money assumes that the demand for real money balances is proportional to income. In this case, the money demand function can be written as: $(M/P)^d = kY$ where $(M/P)^d$ is the demand for real money balances, Y is real income or output and k is a constant. a) Use calculus to illustrate that such a money demand function implies that the income elasticity of money demand is 1. b) Using the more realistic money demand function below, where money demand depends on the nominal interest rate (i) as well as real income, calculate the income elasticity of money demand and the interest elasticity of money demand. (Hint: your answers should be just numbers.) $(M/P)^d = i^{-0.1}Y^{0.7}$ c) Explain in a few sentences, what these elasticities mean, paying attention to both the sign and the magnitude of the answers you calculated in part b).

(30 pts.) The following second order gas phase reaction, A ? B is conducted in a packed-bed reactor with 20kg catalyst. The feed stream is supplied at a flow rate of 30 m³/min with A in a concentration of 1 mol/liter at a temperature where the rate constant is equal to 0.005 m$^3$.mol$^{-1}$.kg$^{-1}$.min$^{-1}$. The inlet pressure is 50 atm. The pressure in a packed-bed reactor can be described by $\frac{P}{P_0} = (1 - \alpha W)^{1/2}$, where W is the catalyst weight and $\alpha = 0.045$ kg$^{-1}$ a) Calculate the exit conversion, pressure and volumetric flowrate b) If the reaction was A ? 0.5B, how would this affect the conversion. Note that this problem has coupled differential equations and would require a numerical solution. Estimate the effect of the new reaction stoichiometry on final conversion compared to the solution in a) c) Instead of 1 packed-bed reactor with 20 kg catalyst, you can connect 10 reactors in parallel (having 2 kg catalyst each, and the inlet flowrate of 30 m³/min would be split equally between the reactors). Would this increase the conversion? Calculate the conversion to justify your answer. $\alpha$ is the same as in part a)
