The following pairs have to be ranked in order of increasing boiling point. Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form. When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure. Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the functional group present in the molecule. If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low. The boiling point of a liquid is the temperature at which its vapor pressure is equal to the external pressure.

Answer 1

Question

Chapter 11, Problem 36GQ

Interpretation Introduction

Interpretation: The following pairs have to be ranked in order of increasing boiling point.

Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the functional group present in the molecule.

If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.

The boiling point of a liquid is the temperature at which its vapor pressure is equal to the external pressure.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
