In an experimental setup, streams containing pure components $(A)$ and $(B)$ are mixed in a well$-$insulated mixer at a constant temperature of $80C.$ This mixing process releases heat. The experiment measures the amount of heat that is removed to maintain the temperature at $80C.$ By analyzing this data $($table below$),$ determine the enthalpy of mixing $(\frac{J}{m}ol)$ as a function of the mole fraction of $A(x_A)$ in the mixture, and plot the results $($Molar mass of A and $B$ are $120\frac{g}{m}ol$ and $58\frac{g}{m}ol,$ respectively$).$
