Chapter 8, Problem 8.21P

Interpretation Introduction

(a)

Interpretation:

The heat required for the given operation should be calculated

Concept introduction:

The rate of heat generated can be calculated using the equation,

$Q=n\Delta H$

Where, n = molar flow rate and $\Delta H$ = change in enthalpy

Interpretation Introduction

(b)

Interpretation:

The heat required for the given operation using Kopp’s rule and the percentage error should be calculated.

Concept introduction:

Kopp’s rule is used in estimating the value of Cp for a solid or a liquid.

Kopp’s rule defines that the Cp is the sum of contributions by the individual elements given in table B.10 for a molecular compound.
