Calculate the Gibbs energy of mixing when a mixture of 1.00 mol of MCH and 3.00 mol of THF is prepared. When the excess Gibbs energy of solution of tetrahydrofurane (THF) and methyl cyclohexane (MCH) at 303.15 K was found to fit the expression
GE = nRTx(1 -x){0.4857 - 0.1077(2x - 1) +0.0191(2x - 1)2} Where x is the mole fraction of the methyl cyclohexane and n is the total number of moles in the mixture.
