Determine the entropy, Salpha (T,P)

Consider a simple one component system at a constant pressure \( P \). The chemical potential for the phase \( \alpha \) varies with temperature \( T \) and pressure \( P \) according to the following expression:

\[
\mu_\alpha(T, P) = \mu_{\alpha 0} - s_{\alpha 0} T - \frac{1}{2} c_\alpha T^2 + v_{\alpha 0} P - \frac{1}{2} k_\alpha P^2 + w_\alpha TP,
\]

where \( \mu_{\alpha 0}, s_{\alpha 0}, c_\alpha, v_{\alpha 0}, k_\alpha \) and \( w_\alpha \) are constants that differ for each phase, \( \alpha \).

1. Determine the following quantities for phase \( \alpha \) as a function of temperature \( T \) and pressure \( P \):
