Which statement is true if the hrxn of a reaction is positive? a.)the reaction is endothermic. b.)the reaction is exothermic. c.)there is more reactant than product. d.)there is more product than reactant.

The correct answer is Option A.

Explanation:

Endothermic reactions are defined as the reactions in which potential energy of the reactants is less than the potential energy of the products. The total enthalpy change of the reaction comes out to be positive. Energy is absorbed during this reaction.

Exothermic reactions are defined as the reactions in which potential energy of the products is less than the potential energy of the reactants. The total enthalpy change of the reaction comes out to be negative. Energy is released during this reaction.

From the above information, the correct answer is Option A.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
