Which equation or rule can be used to estimate the pseudo-critical properties of mixtures based on the pure-component critical constants? select one: a. newton's correlations b. soave-redlich-kwong equation c. kay's rule d. van der waals equation of state e. peng-robinson

c. Kay's rule

Explanation:

Kay's rule -

The rule is used to determine the pseudo reduced critical parameters of mixture , with the help of using the critical properties of the components of a given mixture .

The equation for Kay's rule is as follows ,

PV = Z RT

Where Z = The compressibility factor of the mixture .

Hence from the given options , the correct answer is Kay's rule .
