Question

Which statement is true if the (triangle here)Hrxn 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 1

The reaction is endothermic.

Answer 2

The reaction is endothermic.

Step-by-step explanation:

A positive enthalpy change of reaction tells us that the reaction is positive. That is to say the energy that the reaction took in to break bonds is greater than the energy it gave out when it was forming bonds so the net change is positive.
