(a)
Interpretation:
Balanced chemical equation to be identified.
Concept Introduction:
For balancing the reaction number of mole of reactant need to be equivalent to number of mol of product.
(b)
Interpretation:
More energy liberated by the reaction per mol of reactant to be identified.
Concept Introduction:
Endothermic reaction involves the absorption of energy which helps in further proceeding of the reaction to produce good yield of product.
Exothermic reaction involves the liberation of energy which helps in further proceeding of the reaction to produce good yield of product.
(c)
Interpretation:
More energy liberated by the reaction per gram of reactant to be identified.
Concept Introduction:
Endothermic reaction involves the absorption of energy which helps in further proceeding of the reaction to produce good yield of product.
Exothermic reaction involves the liberation of energy which helps in further proceeding of the reaction to produce good yield of product.
