Which of the following must be true about a reaction if it is only spontaneous at high temperatures? it is exothermic, with both negative enthalpy and entropy changes. it is endothermic, with both positive enthalpy and entropy changes. it is exothermic, with a negative enthalpy and positive entropy change. it is endothermic, with a positive enthalpy and negative entropy change. 2. if the reaction between two solutions has a positive enthalpy change, which of the following best describes the reaction? (2 points) it is exothermic and heat is added to the system. it is endothermic and heat is added to the system. it is exothermic and heat is lost to the surroundings. 3) which statement below best describes the relationship of the reaction below? (2 points) 3a + b yields 2ab the rate of formation of ab is twice the disappearance of a. for every two ab produced, the reaction requires three a. the rate of disappearance of a is two times the formation of ab. 4) describe how you would use the information depicted on the potential energy diagram below to determine the amount of required activation energy and the enthalpy change of the reaction. (2 points) (see chart)
