Identify the correct statement for change of Gibbs energy for a system ($\Delta G_{\text{system}}$) at constant temperature and pressure:

A solution containing $10{\text{g per dm}}^3$ of urea (molecular mass = $60{\text{g mol}}^{-1}$) is isotonic with a $5\%$ solution of a non-volatile solute. The molecular mass of this non-volatile solute is :

A plot of $\log \frac{x}{m}$ versus $\log p$ for the adsorption of a gas on a solid gives a straight line with slope equal to :
