1. Match each combining form in Column A with a meaning in Column C by inserting the appropriate number in Column B Column A Column B Column C (a) cervic/o ….
Calculate the free energy change of mixing, G”, for the process.
1. nA moles of gas A and ne moles of gas B are mixed at constant temperature and pressure. Calculate the ratio of A and B which minimises the free energy of the mixture. Assume that both A and B are ideal gases.
2. A lm’ cylinder contains H&) at 298K and latm, and is connected to another cylinder which contains 3m3 O,(g) at 298K and 0.8atm. When the valve is opened, the gases diffuse into each other and form a homogeneous mixture under isothermal conditions. Calculate the free energy change of mixing, G”, for the process. Assume the gases behave ideally.
