Concept explainers
(a)
Interpretation : The amount of heat required to form 3.00 g of NO should be calculated.
Concept Introduction : The enthalpy of
(b)
Interpretation : The complete equation for the decomposition of NO should be determined.
Concept Introduction : The enthalpy of chemical reaction indicates the energy absorb or release during the reaction. When we reverse any chemical reaction the sign of ΔH will also reverse but the value of ΔH will remain same.
(c)
Interpretation : The amount of heat released when 5.00 g of NO decomposes to form nitrogen and oxygen gas.
Concept Introduction : The enthalpy of chemical reaction indicates the energy absorb or release during the reaction. When we reverse any chemical reaction the sign of ΔH will also reverse but the value of ΔH will remain same.
