Question
Chapter 6, Problem 99E
Interpretation Introduction
Interpretation:
The volume of methane burned when given energy of methane required to heat the home should be calculated.
Concept Introduction:
Enthalpy change: It is defined as the amount of heat released or absorbed by the
Specific heat capacity: It is the amount of heat required by the substance to increase temperature of the 1 kilogram of the substance by 1 kelvin.
Calorimeter: It is the device used to measure the heat involved in the chemical reaction.
The heat released by the reaction is measured in calorimetry by using the following formula.

Potential Energy (kJ)
1. Consider these three reactions as the elementary steps in the mechanism for a chemical reaction.
AH = -950 kJ
AH = 575 kJ
(i) Cl₂ (g) + Pt (s) 2C1 (g) + Pt (s)
Ea = 1550 kJ
(ii) Cl (g)+ CO (g) + Pt (s) → CICO (g) + Pt (s)
(iii) Cl (g) + CICO (g) → Cl₂CO (g)
Ea = 2240 kJ
Ea = 2350 kJ
AH = -825 kJ
