For the acetone(1)/methanol(2) system, a vapor mixture for which z1 = 0.25 and z2 = 0.75 is cooled to temperature t in the two-phase region and flows into a separation chamber at a pressure of 1 bar. if the composition of the liquid product is to be x1 = 0.175, what is the required value of t and what is the value of y1? for liquid mixtures of this system, to a good approximation,

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
