Chapter 8, Problem 8.50SP

Interpretation Introduction

Interpretation:

$\Delta H$ for the given reaction has to be calculated.

Concept Introduction:

Specific heat is the heat required to raise the temperature of $1g$ of a substance by accurately $1°C.$

Specific heat is denoted by ‘c’ and the formula is,

$c=\frac{q}{m\times \Delta T}$

Where,

$\begin{array}{l}q=quantity\text{ of heat added}\\ \Delta T=change\text{ in temperature}\\ \text{m}\text{= mass of the substance}\end{array}$

Enthalpy corresponds to heat content of the system and it is represented by ‘H’ and it is the sum of internal energy ‘E’ and product of volume and pressure,

$H=E+PV$

$\Delta H$ refers to change in enthalpy.  $\Delta H$ can be calculated using the formula,

$\Delta H=\frac{q}{n}$

Where,

$\begin{array}{l}\text{n }\text{= no}\text{. of moles}\\ q=\text{ heat of the reaction}\end{array}$
