When reversing the direction of a reaction that has a change in enthalpy of 80 kJ you must: double the enthalpy of the reaction halve the enthalpy of the reaction change the sign on the enthalpy of the reaction from + to - to indicate the reaction is now exothermic. change the sign on the enthalpy of the reaction from + to - to indicate that the reaction is now endothermic.

In order to break water into hydrogen and oxygen, water is heated to more than 500°C. Which kind of reaction is this and why? It is exothermic because heat needs to be released by the reactants to form the products. It is endothermic because heat needs to be released by the reactants to form the products It is exothermic because heat needs to be absorbed by the reactants to form the products. It is endothermic because heat needs to be absorbed by the reactants to form the products.
