Question

Calculate the liquid-phase molar volume of each of the following species at the temperature indicated. Calculate the percent error from the measured values reported and explain the trend in results. (Rackett Equation)

a. Methane at 111K; v_measured = 37.7 cm³/mol
b. Ethane at 183K; v_measured = 54.8 cm³/mol
c. N-Octane at 293K; v_measured = 162.5 cm³/mol
d. Water at 293K; v_measured = 18.0 cm³/mol
e. Acetic Acid at 293K; v_measured = 57.2 cm³/mol

Answer 1

FROM PERCENTAGE ERRORS MEASURED IN EACH PART, IT IS CLEAR THAT RACKETT EQUATION GIVES FAIRLY ACCURATE RESULT WITH LOW ERROR FOR METHANE, ETHANE & N OCTANE. HOWEVER,, EQUATION DOES NOT GIVE CORRECT RESULT FOR WATER AND ACETIC ACID.

DEAR STUDENT, ANSWER MAY VARY SLIGHTLY DUE TO DIFFERENT VALUES OF CRITICAL PROPERTIES IN DIFFERENT SOURCES AVAILABLE. KINDLY CONSIDER THAT. DEAR STUDENT, IF YOU HAVE ANY QUERY PLEASE ASK ME. I SHALL DEFINTIELY HELP IN RESOLVING YOUR QUERY. THANK YOU.
