Homework Statement
so I've calculated Pc, Vc and RTc the critical pressure volume and temperature from van der Waals equation of state; (P + aN^2/V^2)(V-Nb) = NRT by solving the three equations from this and dP/dV = 0 and d^2P/dV^2 = 0.
But now I have to calculate the critical exponents beta, gamma and delta. I have no idea how to proceed, and this is assessed coursework, so please no one do it for me due to plagiarism etc... but if someone could point me in the right direction that'd be great.
I get Pc = a/27b^2
Vc = 3Nb
RTc = 8a/27b
