Q10: At 98C, a mixture of 3mol of 1,2 -dibromoethane (C2H4Br2,M=186g/mol) and 2mol of 1,1-dibromopropane (C3H6Br2,M=200g/mol) forms an ideal solution, which obeys Raoult's law in
Q10: At 98C, a mixture of 3mol of 1,2 -dibromoethane (C2H4Br2,M=186g/mol) and 2mol of 1,1-dibromopropane (C3H6Br2,M=200g/mol) forms an ideal solution, which obeys Raoult's law in terms of its behavior for all components in the solution. It is known that at this temperature, the vapor pressures for pure C2H4Br2 and pure C3H6Br2 are 22.9kPa and 16.8kPa respectively. Calculate for this ideal solution (1) the partial vapor pressure for each component and the total vapor pressure; (2) the percentage weight of C2H4Br2 in the gas phase (assume that the vapor behaves like an ideal gas); (3) the changes in entropy and Gibbs energy associated with mixing the two pure components to form the ideal solution
