This is the stem. In an endothermic reaction , the reactants have a BLANK total bond energyThis means the relative potential energy of the reactants is BLANK than the relative potential energy of the products. The reaction BLANK energy. 1. higher 2. lower 3.absorbs 4.releases 5. potential 6.non existent fill in the blank cant use them twice

1. higher

2. lower
