At atmospheric pressure, acetone (1) and chloroform (2) form an azeotrope that boils at 64.6 °C and has a mole fraction of acetone in the liquid of 0.335. The saturation vapor pressures of acetone and chloroform at 64.6 °C are 1.31 and 0.98 atm, respectively.(i)Find the activity coefficients of acetone and chloroform at the azeotrope.(ii)Find the value for GE in kcal/mol.(iii)Using the calculated values, find the composition of vapor over liquid at 64.6 C that contains 12 mol% acetone. Use Van laar equation.(iv)Find the total pressure of the solution at the above condition. Given: van Laar model is as follows RTx1x2GE=1Bx1+1Ax2n1=A(1+ABx1x2)2n2 =B(1+BAx2x1)2A=n1[1+x2x1n2n1]2B=n2[ 1+x1x2n1n2

Astudent made a graph plotting the progress of a reaction over time. the student forgot to label the y-axis of the graph. a graph is shown with two graph lines. one graph line starts at a higher position on the y axis and slopes downwards towards the right. the other graph line starts at a lower position on the y axis and slopes upwards towards the right. the two graph lines stop short of intersecting each other and continue as separate lines which gradually become straight and parallel to the x axis. a vertical line is shown at a point where the two graph lines finally became parallel to the x axis. this vertical line is labeled equilibrium. the title on the x axis is time and an arrow pointing towards the right is shown above time. the title on the y axis is left blank. what best explains the label that the student should use on the y-axis? amount, because as the amount of product decreases, the amount of reactant increases over time. reaction rate, because forward and backward reaction become equal at equilibrium. amount, because the amounts of reactants and products become constant after equilibrium is reached. reaction rate, as the rate of forward reaction increases and rate of backward reaction decreases over time.
