The reaction between ethylene and hydrogen bromide to form ethyl bromide is carried out in a continuous reactor. The product stream is analyzed and found to contain 51.7 mol% C$_2$H$_5$Br and 17.3 mol% HBr. The feed to the reactor conains only ethylene and hydrogen bromide. Calculate the fractional conversion of the limiting reactant and the percentage by which the other reactant is in excess. If the molar flow rate of the feed stream is 185 mol/s, what is the extent of reaction? Fractional Conversion: Percent Excess of non-limiting reactant: Extent of reaction:

membrane excitement, firing properties, and spike frequency. 4. You are studying a myelinated axon with the following values. $P_K$=0.95, $K_{in}$=200mM, $K_{out}$=5mM, $P_{Na}$=0.05, $Na_{in}$=5mM, $Na_{out}$=130mM. a) The Na+ channels in a node of Ranvier open causing a 30 nS increase in conductance. What is the total current? [hint: $I = g (V_m - E_{Na})$, S is the unit for conductance (g).] b) What is the depolarization caused by this current, if the $R_m$=8 M?? c) What will be the depolarization at the next node if the $R_m$ along the internode is 1M?*cm$^2$ and the $R_i$ is 10M?*cm, and the internode is 0.1cm long? [hint: $V_x = V_0 e^{x/?}$, $? = \sqrt{R_m/R_i}$] d) What parameter changes in a demyelinating disease? Why? What will happen to action potential propagation?
