Abstract

Theoretical values of ultrasonic velocity in the binary mixtures of chlorobenzene with benzene have been evaluated at different temperatures from 303.15 K-323.15 K using Nomoto's relation, ideal mixture relation, Junjie's method, collision factor theory and free length theory. Theoretical values were compared with the experimental values and the validity of the theories was checked by applying the chi-square test for goodness of fit and by calculating the average percentage error (APE).

Highlights

Measurement of ultrasonic velocity gives the valuable information about the physicochemical behavior of the liquid and liquid mixtures
Semi-empirical formula and theories are available for the theoretical computation of ultrasonic velocity in liquid and liquid mixtures[1,2,3,4,5]
The ultrasonic velocity was measured at different temperatures from 303.15 K-323.15 K using a single crystal interferometer with a high degree of accuracy operating at a frequency of 2 MHz

Summary

Introduction

Measurement of ultrasonic velocity gives the valuable information about the physicochemical behavior of the liquid and liquid mixtures. Semi-empirical formula and theories are available for the theoretical computation of ultrasonic velocity in liquid and liquid mixtures[1,2,3,4,5]. The best suitable theory for the given molecular system under study is picked out by calculating the average percentage error and chi-square test.
