Chapter 8, Problem 8.50P

Interpretation Introduction

(a)

Interpretation:

Estimate a linear expression for Cp (T) and calculate enthalpy change for the transition of NaCl for the given case.

Concept introduction:

Heat capacity of solid NaCl at temperature T is given by,

$C_p\left(J/mol{.}^{0}C\right)=a+bT$

Where, ‘a’ and ‘b’ are constants and T is temperature.

Interpretation Introduction

(b)

Interpretation:

Calculate the required heat input for the given case.

Concept introduction:

Heat capacity of solid NaCl at temperature T is given by,

$C_p\left(J/mol{.}^{0}C\right)=a+bT$

Where, ‘a’ and ‘b’ are constants and T is temperature.

Interpretation Introduction

(c)

Interpretation:

How long does the process take to heat?

Concept introduction:

Heat capacity of solid NaCl at temperature T is given by,

$C_p\left(J/mol{.}^{0}C\right)=a+bT$

Where, ‘a’ and ‘b’ are constants and T is temperature.
