You are running a manufacturing process where a mole fraction of 0.40 species 1 in a binary mixture of 1 and 2 is required at a fl ow rate of 5 mol/s and a temperature of 300 K. This is achieved by mixing pure streams of 1 and 2. The stream of pure 2 fl ows into the mixer at a temperature of 300 K. The molar enthalpy of mixing of species 1 and 2 is given by:

Assuming an adiabatic mixing process, what is the inlet temperature required for stream 1 to achieve the desired outlet stream temperature?
