which statement is true if the δhrxn of a reaction is positive? the reaction is endothermic. the reaction is exothermic. there is more reactant than product. there is more product than reactant.

which statement is true if the δhrxn of a reaction is positive? the reaction is endothermic. the reaction is exothermic. there is more reactant than product. there is more product than reactant.

Answer

Brief Explanations:

In thermochemistry, $\Delta H_{rxn}$ (enthalpy change of a reaction) is positive for endothermic reactions. Endothermic reactions absorb heat from the surroundings. Exothermic reactions have a negative $\Delta H_{rxn}$. The amount of reactant and product is not determined by the sign of $\Delta H_{rxn}$ but by factors like reaction stoichiometry and equilibrium.

Answer:

The reaction is endothermic.
