Concept explainers
(a)
Interpretation: Whether the given reaction is exothermic or endothermic should be determined.
Concept Introduction : The reaction which requires energy for the conversion of reactant to product is called as endothermic reaction whereas the reaction that releases some amount energy during the conversion of reactant to product is called as exothermic reaction.
(b)
Interpretation: The amount of energy in kilojoules released when 2.50 mol of H2O2 reacts should be determined.
Concept Introduction : The reaction which requires energy for the conversion of reactant to product is called as endothermic reaction whereas the reaction that releases some amount energy during the conversion of reactant to product is called as exothermic reaction.
(c)
Interpretation: The amount of energy in kilojoules released when 275 g of O2 produced should be determined.
Concept Introduction : The reaction which requires energy for the conversion of reactant to product is called as endothermic reaction whereas the reaction that releases some amount energy during the conversion of reactant to product is called as exothermic reaction.
