Chapter 11, Problem 124QP
Interpretation Introduction

Interpretation:

Using the given statement, the weak and strong electrolyte substance is to be identified.

Concept Introduction:

The vapour pressure is the pressure of a vapour in equilibrium with its liquid phase at a given temperature in a closed system. Thus, there is equilibrium between the molecules at the surface of the liquid and with the gas phase molecules.

When a solute is added in the liquid, some of the solvent molecules at the surface are replaced by the solute molecules. As a result, the number of molecules in the gas phase is decreased leading to the decrease in vapour pressure.

Strong electrolytes are easily dissociated than weak electrolytes. Thus, strong electrolytes give a greater number of ions in solution which leads to the decrease in vapor pressure.

5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!) (c) Explain under what conditions for the ideal gas the compressibility is higher or lower, and why that makes sense.
19. (3 pts) in Chapter 7 we will see a reaction of halocyclohexanes that requires that the halogen occupy an axial position with this in mind, would you expect cis-1-bromo-3-methylcyclohexane or trans-1-bromo-3-methylcyclohexane to be more reactive in this reaction? Briefly explain your choice using structures to support your answer. Mere-eries-cecleone) The tran-i-browse-3-methylcyclohexione
