Concept explainers
(a)
Interpretation:
If the stoichiometric coefficient of the first reactant in each reaction is equal to 1 then the heat of the following reaction in kJ/mol should be calculated:
Nitrogen dioxide is form by the reaction of nitrogen and oxygen.
Concept Introduction
In this we use the basic concept of chemical reaction to find the heat liberated by it during the process and Hess law to calculate ΔHt 0
(b)
Interpretation:
If the stoichiometric coefficient of the first reactant in each reaction is equal to 1 then the heat of the following reaction in kJ/mol should be calculated:
Concept introduction:
In this we use the basic concept of chemical reaction to find the heat liberated by it during the process and Hess law to calculate ΔHt 0
(c)
Interpretation:
If the stoichiometric coefficient of the first reactant in each reaction is equal to 1 then the heat of the following reaction in kJ/mol should be calculated:
Carbon dioxide + water vapor is form by the reaction of liquid n-heptane + oxygen
The stoichiometric equation for the formation of reactant and product should be determined along with the calculations of ΔHr 0 by using the Hess’s law.
Concept introduction:
In this we use the basic concept of chemical reaction to find the heat liberated by it during the process and Hess law to calculate ΔHt 0
(d)
Interpretation:
If the stoichiometric coefficient of the first reactant in each reaction is equal to 1 then the heat of the following reaction in kJ/mol should be calculated:
Liquid sodium sulfide + carbon dioxide is form by the reaction of liquid sodium sulfate + carbon monoxide
Concept introduction:
In this we use the basic concept of chemical reaction to find the heat liberated by it during the process and Hess law to calculate ΔHt 0
