A binary mixture of species a and b behaves as an ideal gas at 300 K and 1 bar. Calculate the partial molar Gibbs energy of species a, Ga, and the total solution Gibbs energy, g, at the following compositions. The pure species Gibbs energy for species a is 225 kJ/mol and for species b is 240 kJ/mol.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

5 structural isomers

the isomers are:

n-exane :   ch3ch2ch2ch2ch2ch3

2-methylpentane :   ch3ch(ch3)ch2ch2ch3

3-methylpentane :   ch3ch2ch(ch3)ch2ch3

2,3-dimethylbutane :   (ch3)2chch(ch3)2

2,2-dimethylbutane :   (ch3)3cch2ch3
