 GERG 2004 Monograph equation 7.55: If the \(x_i\) are all independent

\[ \left(\frac{\partial}{\partial x_j}\left(n\left(\frac{\partial \rho_r}{\partial n_i} \right)_{n_j}\right)\right)_{x_i} = \left(\frac{\partial^2\rho_r}{\partial x_j \partial x_i}\right)-\left(\frac{\partial \rho_r}{\partial x_j}\right)_{x_i}-\sum_{k=0}^{N-1}x_k\left(\frac{\partial^2\rho_r}{\partial x_j \partial x_k}\right) \]

Gernert, JPCRD, 2014, A28 If \(x_N = 1-\sum x_i\):

\[ \left(\frac{\partial}{\partial x_j}\left(n\left(\frac{\partial \rho_r}{\partial n_i} \right)_{n_j}\right)\right)_{x_i} = \left(\frac{\partial^2\rho_r}{\partial x_j \partial x_i}\right)-\left(\frac{\partial \rho_r}{\partial x_j}\right)_{x_i}-\sum_{k=0}^{N-2}x_k\left(\frac{\partial^2\rho_r}{\partial x_j \partial x_k}\right) \]
