Charlotte P. Gilman's "The Yellow Wallpaper."

In "The Yellow Wallpaper" what does the woman behind the wallpaper represent? And why does the narrator come to identify with her?

A liquid containing 60 mol% toluene (Tb = 110 °C) and 40 mol% benzene (Tb = 80 °C) is continuously distilled in a single-equilibrium-stage unit at atmospheric pressure. What percentage of benzene in the feed leaves in the vapour if 90% of the toluene entering in the feed leaves in the liquid. Assume a relative volatility of 2.3 and obtain the solution graphically. The solution may require an iterate approach.

True/False?

Part 1.The rate law for the elementary reaction A + B → products might not be R = k[A][B].

Part 2. If we know the mechanism of a reaction including the values of the elementary rate constants, we can find the rate law (assuming the differential equations can be solved).

Part 3. The Arrhenius equation holds exactly.

Part 4. In homogeneous catalysis, doubling the catalyst concentration will change the rate.

Part 5. A catalyst does not appear in the overall reaction.

Balanced Equation:

Recall that an emission transition involves a jump from an upper energy level down to a lower energy level. With this in mind, what quantum number do lines of the Lyman series have in common? The Balmer series? The Paschen series? How can we designate a set of lines as a “series”?
