Which statement best describes the reaction pathway graph for an exothermic reaction but not an endothermic reaction? it has a hill in the middle that is the highest point. it has a valley in the middle that is its lowest point. the reactants are higher in energy than the products. the products are higher in energy than the reactants.

 The reactants are higher in energy than the products

Explanation:

Every reaction needs a certain minimum energy to get converted to products called as activation energy. It is represented by a hill in the middle that is the highest point.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and for the reaction comes out to be positive.

the answers would be

the first one and the second one

the answer is 0.42 is that is an option. this question provides no info
